SMRT36
Megger Relay Test System
Current Amplifier - Extended power Range
The SMRT current amplifier provides a unique flat power curve from
4 to 30 Amperes per phase to permit testing of electromechanical
high impedance relays, and other high burden applications, with an
extended operating range up to 60 Amperes at 300 VA rms.
AC Voltage Output
Outputs are rated with the following Ranges:
Output Volts
Power Max I
30 Volts 150 VA 5 Amps
150 Volts 150 VA Variable 2
300 Volts 150 VA 0.5 Amps
DC 150 Watts
Duty Cycle: Continuous
With two voltages in series
The output voltage and power doubles to provide 600 volts at
300 VA.

“powerV TM ” Voltage Amplifier - Extended power Range
The SMRT voltage amplifier provides a flat power curve from 30
to 150 Volts in the 150V range to permit testing of high current
applications such as panel testing.

SpECIFICATIONS 1
Input power
The input voltage rating varies depending upon the style number.
Universal units, the input voltage may be from 100 to 240 VAC,
± 10%, 50/60 Hertz. CE Marked units, the input voltage may be
from 220 to 240 VAC, ± 10%, 50/60 Hertz. Total maximum output
power will be limited for CE marked units . Input current required
varies with the number of output modules in use, load, and input
voltage value. With three VIGENS, the maximum input power is
1800VA.
Outputs
All outputs are independent from sudden changes in mains voltage
and frequency, and are regulated so changes in load impedance do
not affect the output. All amplifier outputs are isolated or floating.
The SMRT units can be ordered with the amplifier common returns
tied to chassis ground as an option.
Output Current Sources
The SMRT36 with three VIGEN modules can provide up to
six current sources; three high current/high power, and three
convertible channels providing lower current/high power. The per
channel output current and power ratings are specified in AC rms
values and peak power ratings.
