    The relating standards: EN60947-1 VDE0660-100 EN60898-2

     

    Test bench for DC circuit breakers

The test bench is available as 100% turnkey solution for AC and DC circuit breakers.

 

THE FUNCTIONAL PRINCIPLE for Circuit Breaker Testing
Main components of the circuit breaker test system:
- Signal generator SyCore
- Current amplifier
ESN or DCS
- Power adjustment
IT including range switching
- Supervising- and protection unit
- Adaptation units
- System control unit
SPS/S7/1200
- Operator-PC with Software
 

CURRENT AMPLIFIER ESN SERIES (thermal and magnetic testing):

The ESN series current amplifiers have a very low harmonic distortion (typically <0.5%) and frequency ranges 45Hz-65Hz / 15Hz-150Hz / 45Hz-450Hz /DC. The specified continuous power relates to the requirements of the thermal testing. The available short-time power capability (for the magnetic tripping characteristic testing) is 3-times the continuous power of the ESN series. As an option the short-time power capability can be extended to 6.5 times of the amplifiers continuous power.
The ESN amplifier series has various continuous power ranges:
- 100VA - 200VA - 400VA - 500VA - 700VA - 1000VA - 1500VA
- 3000VA - 4500VA - 5000VA - 6000VA - 7500VA - 9000VA
- 15000VA - 30000VA
Possible current-/voltage combinations
ESN 1500: 5A/600V, 20A/160V, 80A/40V, 260A/12V, 650A/9V, 1300A/4.5V
ESN 4500: 5A/500V, 25A/150V, 50A/75V, 100A/37V, 300A/37V, 500A/22V, 1000A/22V, 1600A/14V

CURRENT AMPLIFIER ESN SERIES (thermal and magnetic testing):

CURRENT AMPLIFIER DCS SERIES (thermal testing):


The DCS series offers modular 5000VA power stages, optional parallel connection is available. CURRENT AMPLIFIER DCS SERIES (thermal testing):A power adjustment unit is available for both amplifier series.
