AUXILIARY POWER SUPPLY

power

DC Power

• Measuring bidirectional power flow

R: 24 V DC

• DC output containing little ripple is ideal for computer

(Operational voltage range 24 V ±10 %, ripple 10 %p-p max.)

input

• "Time division multiplication" method accepts distorted

waveforms

GENERAL SPECIFICATIONS

Construction: Rack-mounted; terminal access via screw

terminals on the front and connector on the rear; terminal

cover provided

Typical Applications

• Centralized monitoring and control of power management

system in a manufacturing facility or building

• SCR – Silicon Controlled Rectifier

Connection

Input: M3.5 screw terminals (torque 0.8 N·m)

Output: Connector

Auxiliary power: Supplied from connector

Screw terminal: Nickel-plated steel

Isolation: Voltage input to current input to output to

auxiliary power

Computation: Time division multiplication

Overrange output: Approx. -10 to +120 %

Zero adjustment: -5 to +5 % (front)

Span adjustment: 95 to 105 % (front)

INPUT SPECIFICATIONS

Frequency: 50 or 60 Hz

MODEL: 17WT–[1][2]6–R

• Voltage Input

ORDERING INFORMATION

• Code number: 17WT-[1][2]6-R

Specify a code from below for each [1] and [2].

(e.g. 17WT-116-R)

Operational range: 0 – 120 % of rating

Overload capacity: 150 % of rating for 10 sec., 120 %

continuous

• Current Input

• Wattage range (e.g. 0 – 980 W)

Operational range: 0 – 120 % of rating

Overload capacity: 1000 % of rating for 3 sec., 200 % for 10

sec., 120% continuous

■ How to determine Wattage Range

Calibration Range [W] = Measuring Wattage ÷ ((VT Ratio) ×

(CT Ratio))

[1] CONFIGURATION

1: 3-phase / 3-wire

2: Single-phase / 2-wire

3: Single-phase / 3-wire

Check that the required calibration range is within the

available range in the table. Specify this range when

ordering.

[2] INPUT (unbalanced load)

1: 110 V / 5 A AC

[Example]

3-phase / 3-wire, measuring wattage 750 kW,

VT 3300/110 V, CT 250/5 A

2: 110 V / 1 A AC

3: 220 V / 1 A AC

750 × 10 [W] ÷ ((3300÷110) × (250÷5)) = 500 [W]

4: 220 V / 5 A AC

A: 100 V / 200 V / 1 A AC (single-phase / 3- wire)

B: 100 V / 200 V / 5 A AC (single-phase / 3- wire)
