High Accuracy, Low Noise Mid-to-High Voltage DC-DC Converter
10,000V, 15,000V NHV Series
The NHV series is our mid-to-high voltage DC-DC converter featuring high accuracy and low noise. Its design for
minimizing line regulation, load regulation, temperature drift and time-course drift enables highly accurate and stable
voltage to be provided. A hexahedron metal shield case ensures low noise along with a selection of a circuit suitable for
noise suppression. Output voltage is adjustable by external voltage or an external variable resistor. A built-in short-circuit
and over current protection ensure high reliability and a long life.

8. Functions
8-1 Adjustable output voltage
Output voltage can be set by applying 0 to 10V between the terminals for output voltage control, the Vcont
(4Pin) and SGND (3Pin). Avoid setting out of the adjustable output voltage range or it may cause trouble.

8-2 Monitoring output voltage and output current
Output current monitoring terminal, the Imoni (7pin) and output voltage monitoring terminal, the Vmoni (8pin)
generate 0 - 10V proportionate to output of the converter.
An internal impedance of each terminal for monitoring is 1kohm. The internal impedance of each terminal for
monitoring is 1kΩ. Do not allow monitoring current to exceed 2mA

8-3 Reference voltage
Reference voltage output terminal, the Vref (5pin) generates reference voltage of 10V. This terminal is used
when controlling output voltage by a variable resistor (5kΩ min.). Leave this terminal open when output
voltage is adjusted by external voltage. Do not allow reference current to exceed 2mA.

8-4 Overcurrent protection
If output current becomes 105% or more of the rated current value, over current protection (OCP) functions to
lower the output voltage. Since this overcurrent protection is an auto restart type, output will resume upon
release of the overcurrent state.
8-5 ON/OFF control
Output voltage can be turned ON/OFF by opening or short-circuiting between the ON/OFF (6Pin) and the
SGND (3Pin) without turning on/off the input voltage. In the case of not using the ON/OFF control, short-circuit
these two terminals. Use an open collector type.
・Open between 6 and 3 (6V max.):
Output Off
・Short between 6 and 3 (0 – 0.3V, 2mA max.): Output On
8-6 Thermal shutdown
This function works upon the abnormal rise of the ambient temperature or the temperature inside this power
supply to stop the oscillation of the converter and the supply of output power. If the thermal shutdown
functioned, shut down the input and wait some time for the temperature to come down sufficiently (after
eliminating the cause) before reclosing.
