TB-231024-V-102 Variable Voltage Tabletop Power Supply for Switchgear and Protection Relay Trainer

TB-231024-V-102 Variable Voltage Tabletop Power Supply for Switchgear and Protection Relay Trainer

Features:

• Its should enable to supply the electric machines with variable AC and DC single-phase/threephase voltages, protected against over currents and accessible on educational safety terminals of 4 mm
• This unit should include a three-phase voltage regulator and the protection devices against over currents
• It is the natural extension of the basic power supply unit from which it receives the supply voltage protected by the high-sensitivity differential circuit breaker and by the emergency stop device. When used separately, this unit must relate to a voltage source protected by high sensitivity differential circuit breaker;

Mechanical and Electric Parameters:

• The box should be made of sheet steel, chemically treated and painted with epoxy varnish; silkscreen-printed fore plate of aluminium alloy with flush-mounted handles for transport.
• Three-phase voltage regulator of 5 A, AC/DC selector
• Three-phase variable line of 0-430 V – 5 A (single-phase, 0-250 V), protected by magneto-thermal circuit breaker, digital 3-digit voltmeter with voltmeter switch for phase-phase and phase neutral connection, safety terminals
• Variable line of 0-500 Vdc – 6 A (three-phase voltage rectified by 6-diode bridge) AC residue of 4.2%; line protected by magneto-thermal circuit breakers, digital 3-digit voltmeter, safety terminals
