Description
The three-phase DC high-voltage power supply is suitable for the development and testing of frequency converters for railway technology. These are located in development laboratories and test fields, testing institutes, schools and universities. Due to the high DC output voltage, appropriate safety measures have been taken, such as:
- Emergency stop circuit with external inputs and outputs as two-pole potential-free contacts for emergency stop and safety circuits
- Warning lights and additional connection options for external warning lights
- Discharge circuit for the intermediate circuit capacitor
- Earthing disconnector with pneumatic drive for short-circuiting and earthing the DC output
The pneumatic drive short-circuits and grounds the DC output even in the event of a mains voltage failure.
Three-phase DC high-voltage power supplies with separate winding, motor drive and electronic voltage regulation of the output voltage to approx. 1.0 %, with short-circuit-proof DC output
Advantages
- compact and modular design (thus easy expansion possible)
- Control via PowerFormer
- Hazard assessment according to the Machinery Directive possible
- special safety circuit
- no EMC problems

The REOLAB 520 power supplies have the same equipment as the REOLAB 420 DC power supplies, but with an additional separately regulated DC output of 0 – 150 VDC, 30 AC or 50 ADC for the control voltage of the power semiconductors. On request also with built-in UPS, so that the power semiconductors still receive control voltage for a certain period of time even in the event of a power failure.
*Of course, other voltages and power ratings can also be offered after consultation.
In addition, different operating options/operating concepts and industrial interfaces are possible.
All data and configurations can be found in our product datasheet.
