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 switching power supply systems used in railway installations.
- Conforms to: VDE 0552
- Test voltage 3 kV for the primary circuit
- Protection IP 20
- Ambient temperature: 40 °C
UNIQUE SELLING POINT
- Power switch with a 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 analogue voltmeter and air-operated breaker
- Analogue 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)
- Analogue 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
- A discharge circuit for the 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
- The clean sine wave of the AC output voltage
- No EMC interference
- 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 is 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 is possible via the control panel
