RCM60 Series
60 W DC-DC Converters
Functional Description
The converters are designed with two stage topology having a booster at input followed by an active clamp forward converter with
a switching frequency of approximately 140 kHz. The built-in high-efficient input filter together with an inrush limiter circuit ensures
very low inrush current of short duration. An antiparallel diode acts as reverse polarity protection together with the external circuit
breaker or fuse.
The circuitry providing the 20 ms ride through time is located after the input filter and booster stage.
The rectification on the secondary side is provided by rectifier diodes. The output voltage control logic is located on the secondary
side and influences the primary logic and PWM control circuit.
An output ORing FET is available (option Q) for use in a redundant power system architecture. If there are no external circuit
breakers, it is possible to order the converter with incorporated fuse (option F). Because this fuse is not accessible, a serial FET
provides reverse polarity protection (only with option F).
Option D encompasses an output voltage monitor by a solid state relay.

Input Transient and Reverse Polarity Protection
A suppressor diode, varistor and a symmetrical input filter form an effective protection against input transients, which typically
occur in many installations, but especially in battery-driven mobile applications.
If the input voltage has the wrong polarity, the incorporated antiparallel diode causes the external input circuit breaker or fuse to
trip. With option F (incorporated fuse), an active reverse-polarity protection circuit prevents from any damage.
Input Under-/Overvoltage Lockout
If the input voltage is out of range, an internally generated inhibit signal disables the converter to avoid any damage.
Inrush Current and Stability with Long Supply Lines
The converter operates with relatively small input capacitance Ci resulting in low inrush current of short duration.
If a converter is connected to the power source through supply lines with reasonable length (<50 m), no additional measures are
necessary to ensure stable operation.
Only in the case of very long supply lines exhibiting a considerable inductance Lext, an additional external capacitor Cext connected
across the input pins improves the stability and prevents oscillations; see fig. 2.

Primary Shutdown (SD)
The output of the converter may be enabled or disabled by a logic signal (e.g. CMOS) applied between the shutdown pin SD and
SD0 (= Vi–). If the shutdown function is not required, pin SD can be left open-circuit. Voltage on pin SD:

Converter disabled:
12 to 154 V (XRCM), 8 to 40 V (12RCM) or open-circuit
–2 to +2 V
Note: In systems consisting of several converters, this feature may be used to control the activation sequence by logic signals or to enable the
power source to start up, before full load is applied.

Thermal Considerations and Protection
A temperature protection is incorporated in the secondary control logic. It generates an internal protection, which enters output
voltage hiccup mode in case of overtemperature. The converter automatically recovers, when the temperature drops below the limit.
The relationship between TA and TC depends heavily upon the conditions of operation and integration into a system.
Caution: The installer must ensure that under all operating conditions TC remains within the limits stated in table 7.

Series and Parallel Connection
The outputs of several RCM Series converters may be connected in series.
Note: If the sum of the output voltages is greater than 60 V, it cannot be considered as ES1 (Safety Extra Low Voltage) according to the safety
standard IEC/UL 62368-1.
Several RCM models of the same type can be operated in parallel connection. To ensures proper current sharing, the load lines
should have equal length and section. The output voltage exhibits a slight droop characteristic, which facilitates current sharing.
In addition, the output voltage tends to be lowered with increasing temperature.
Redundant Systems
For redundant systems, we recommend the options Q and D, see Options.
LED Indicator
The converters exhibit a green LED “Out OK”, signalling that the output voltage is within the specified range.

60 W DC-DC Converters
Description of Options
General conditions:
- TA = 25 °C, unless TC is specified.
Option D: Output Voltage Monitor
Option D encompasses an output voltage monitor by a solid state relay. When Vo is in range, a solid state relay is activated
(connecting OK1 with OK2). Max. data of relay contacts: 0.2 A /120 VDC
Note: The trigger levels are typ. ±5 % of Vo.
Option Q: ORing FET for Redundant Systems
The outputs of 2 parallel connected converters are separated with ORing diodes (built by FETs). If one converter fails, the
remaining one must be capable to still deliver the full power to the load. If more power is needed, the system may be extended to
more parallel converters (n+1 redundancy).
Current sharing must be ensured by load lines of equal section and length. In addition, a slight droop characteristic of the output
voltage and a negative temperature coefficient improve the load sharing as well.
To keep the losses as small as possible, the ORing diode is replaced by a FET. The voltage drop is approx. 22 mV (not dependent of Io).
Note: In the case of a failing converter, the output voltage is maintained by the redundant converters. However, the failing item should be
identified and replaced. We recommend the Out OK function (option D).
Option F: Incorporated Fuse
The railway standard EN 50155 disadvises fuses in the converters. Consequently, the installer must preview an external fuse or
circuit breaker. However, when this is not possible, an incorporated fuse is available (option F). This fuse is not accessible and will
not trip, except if the converter is defect.
Note: Converters with option F are protected against input reverse polarity by a series FET.

Electromagnetic Emissions
All conducted emissions (fig. 8) have been tested as per EN 55011, group 1, class A. These limits are much stronger than
requested in EN 50121-3-2:2016, table 2.1, and coincide with EN 50121-4:2016, table 1.1. The values in fig. 8 are quasipeak values,
which are always lower then peak values.
The average values must respect a margin of 10 dBµV below the limits for quasipeak.
Radiated emissions have been tested according to EN 55011, group 1, class A. These limits are similar to the requirements of
EN 50121-3-2:2016 and EN 50121-4:2016, both calling up EN 61000-6-4+A1:2011, table 1. The tests were executed with horizontal
and vertical polarization. The worse result is shown in Fig. 9.
Note: The highest frequency of the internal sources of EUT is less than 108 MHz. Hence, Radiated Measurement was made up to 1 GHz.
Non-accredited measurement up to 6 GHz are available on request.

RCM60 Series
60 W DC-DC Converters
Installation Instruction
These converters are components, intended exclusively for inclusion by an industrial assembly process or by a professionally
competent person. Installation must strictly follow the national safety regulations in respect of the enclosure, mounting, creepage
distances, clearances, markings and segregation requirements of the end-use application.
Connection to the system is allowed only with cables having suitable wire section, (see section “Connectors and Pin Allocation”).
Other installation methods may not meet the safety requirements. Check that PE is safely connected to protective earth.
No fuse is incorporated in the converter (except for option F). An external circuit breaker or a fuse in the wiring to one or both
input pins.
Do not open the converters, or the warranty will be invalidated. Make sure that there is sufficient airflow available for convection
cooling and that the temperature of the bottom plate is within the specified range. This should be verified by measuring the case
temperature at the specified measuring point, when the converter is operated in the end-use application. TC max should not be
exceeded. Ensure that a failure of the converter does not result in a hazardous condition.
Standards and Approvals
The RCM Series converters are approved according to the last edition of IEC/EN 62368-1 and UL/CSA 62368-1. They have been
evaluated for:
•
•
•
•
•
•
Class I equipment
Building in
Reinforced insulation between input and output
Basic insulation between input and chassis, input and relay contacts (OK1, OK2) and output to relay contacts (OK1, OK2)
Pollution degree 2 environment
Altitude 3000 m
The converters are subject to manufacturing surveillance in accordance with the above mentioned safety standards and with ISO 9001:2015,
IRIS ISO/TS 22163:2017 certified quality and business management system.
Cleaning Liquids and Protection Degree
The converters are not hermetically sealed. In order to avoid possible damage, any penetration of liquids shall be avoided.
The converters correspond to protection degree IP 30.
Railway Applications
The RCM Series converters have been designed observing the railway standards EN 50155:2017, EN 50121-3-2:2016,
EN 50124-1:2017 and AREMA. All boards are coated with a protective lacquer.
The converters comply with the fire & smoke standard EN 45545:2016, HL1 to HL3.
Insulation Test
The electric strength test is performed in the factory as routine test in accordance with EN 62911, EN 50155:2017, and AREMA.
It should not be repeated in the field, and the Company will not honor warranty claims resulting from incorrectly executed electric
strength tests.
