This SCR Elektroniks make bench is a simpler version of the Contactor Routine Test Bench offered on a multi station system. The speciality of this bench is the amount of current / voltage range options it has with respect to the range, AC / DC, number of terminals and electrical parameters that can be measured.

A single dimmer is used for varying all the types of AC and DC voltages making the product easy to use.

To put it simply, this is another option for manually carrying out tests covered in IEC 60947:

  1. Flashing & Continuity Test
  2. Coil current & Wattage Measurement Test
  3. Pick-up / Drop-off Test
  4. Over Voltage Test

The bench boasts of following source and measurement modules:

  1. 0 – 750 V variable AC output with numerous tappings for a host of current options as desired by the UUT with voltage and current measurement
  2. 0 – 70 V half wave adjustable DC output with voltage and current measurement
  3. 24 V fixed DC output for testing auxiliary circuit of a transformer
  4. 0 – 600 V DC output with voltage and current measurement
  5. 0 – 10 A regulated DC current source for millivolt drop measurement with current and millivolt measurement (4 terminal)
  6. Up to 20 Kilo ohms resistance measurement
  7. Temperature measurement: 2 channel temperature measurement
