SPECIFICATIONS:

Operating Voltage : 230 V AC, 50 Hz ± 10%.
Operating Temp. Range : 0°C to 50°C.
Enclosure : 184 x 96 x 200 mm DIN.

  • Current changes by 1% when the load changes till the voltage on the load reaches a value of 24 V
  • Current read in milliamps on the panel meter
  • Low current range: 1 mA to 20 mA. Current remains constant to 5 parts in 103 as the load is varied till the voltage across the load reaches a value of 15 V.
  • Current read in milliamps up to the first decimal place on the panel meter.
