Adjustable and constant voltage supplies REOLAB 423
High voltage supply with AC-Output
Description
The high-voltage supply unit is intended for testing current converters in the energy sector, as well as testing the entire auxiliary converters and switched power supply systems used in railway installations.
- Conforms to: VDE 0552
- Test voltage 3 kV for primary circuit
- Protection IP 20
- Ambient temperature: 40 °C
Unique Selling Point
- Power switch with magnetic and thermal cut-out in the mains input circuit
- Main contactor for operational switching of transformers
- Emergency Off switch and safety loop with warning lamps
- Air-operated short-circuiting and grounding switch for the DC output
- Viewing window for DC analog voltmeter and air-operated breaker
- Analog meters for V & A in the mains supply (96 x 96 mm format)
- Digital meters for V & A in the AC/DC output (96 x 48 mm format)
- Analog meters for the DC output
- Electronically-controlled voltage stabilization
- Forced zero-position for the variable transformer
- Output protected against short-circuit and overload
- Selectable DC output voltage range
- Discharge circuit for external DC link capacitor
- Pushbutton and indicator lamp (22 mm Ø) for operation
Advantages
- Testing of AC and DC current converters with one unit
- Constant residual ripple over the entire adjustment range of the DC output
- Clean sine wave of the AC output voltage
- No EMC problems
- Control error approx. 1 % for AC and DC outputs
- Fast regulation of voltage variations
- Outputs protected against short-circuit and overload
- Doubled output current at half the DC voltage selectable
- True rms measurements with the digital meters
- System operation possible by means of a control panel not in the immediate vicinity of the HV supply unit
- Grounding possibility provided for the DC output
- Additional control of supplementary equipment possible via the control panel
Technical specifications
- Rated voltage 3 x 400V
- Rated power 0-150 kW/kVA
Of course, other voltages and powers can also be offered after consultation.
In addition, different operating options/operating concepts and industrial interfaces are possible.
