Gdj series precision linear high power DC regulated steady current power supply

Product profile


The GDJ series DC power supply is a large current power supply with three-phase input, high-power DC output, and can reach 400 kW. Due to its excellent electronic characteristics, such as high accuracy, precision and stability, ultra-low striated wave DC power supply can provide high power in the production line, which is a more complete product performance. It has a complete protection line, more can meet the user simple, convenient is there is a need. Compared with switching power supply, it has many advantages such as high accuracy, small striated waves, no high frequency radiation interference and wide use place.


This power supply can be used as a veteran and test for components such as the supply vessel, relay and resistor, as well as for experimental testing of electrical components such as thermistor and motor. At present, many well-known capacitor manufacturing plants, resistor plants and other electronic component production units and R & D units such as scientific colleges, all adopt this series of power sources, which have been highly evaluated.


Performance characteristics:


Specification range: in 300 specifications, optional within 0-50 kV output voltage, 0-500 a output current and 6-400 kW output power


Galvanostat: voltage and current are continuously adjustable from zero to nominal value, galvanostat automatically transitions: 800 V-50 kV from 5% - 10% nominal value


Over flow alarm: alarm current value 0-120% rated continuously adjustable, acousto-optical alarm will be placed when the power output current exceeds the current alarm


Overpressure protection: voltage protection value 0-120% rating is continuously adjustable and trip protection will be tripped when the power output current exceeds the current alarm value


Short circuit protection: allows long-term short-circuit or short-circuit power on in any state of work


Overload protection: power trip protection occurs when the power supply or load fails and the output current exceeds the rating by a factor of 1.5


Short circuit alarm: the power supply acousto-optical alarm (selected) when the output voltage falls below 1% of the nominal value


Automatic discharge: supply capacity load power on discharge (coordination)


Output display: voltage, current simultaneously LED digital tube display


Pulse operation: the adjustable time controller constitutes the DC pulse power supply (coordination)


Intelligent: can connect with computer and make up computer-controlled intelligent power supply (coordination)


Primary use


Aluminum foil, needle guide, corrosion


Electrolytic capacitor rehearsal, tantalum capacitor Capacitation


DC motor testing, aging: EV Motor Testing, aging


Resistor, relay, motor and other electronic devices detection, aging


Everything else requires the use of a DC power supply
