Dexing Magnet Tech. Co., Limited 5) Be sure that each part of the power supply is shut down and waiting for 10 to 20 seconds to enable the high-voltage high-capacity capacitance in this power supply to fully discharge to avoid potential electric shock hazard and the damage of the control circuit when performing the following operations: • Connect or disconnect the power input or output cable. • Connect or disconnect the control/measuring cable. • Adjustment of interior circuit. 6) In order to ensure the personal safety of users and operators and the warranty right of the owner of the power supply,...

Dexing Magnet Tech. Co., LimitedII. General of Functions This power supply features high performance, digital control and bipolar constant current, and can be widely used for the excitation of electromagnet and Helmholtz coils to generate smooth, steady and controlled magnetic field. 1) Be able to provide two modes of control and adapt to different application environment: • Controlled by a computer through UART (RS232) interface. 2) Multiple protection functions. Comprehensive protection for the power supply shall be provided considering the factors, such as electric supply status, cooling status...

Dexing Magnet Tech. Co., Limited • The rapidest change rate of output current may reach 50A/s, and the power supply may adjust to restrict the output rate of the reactive load according to the current and power. • With non-output switch reversing, current can smooth the zero crossing point. 5) As a series, GP may select different input and output parameters according to the difference of the application loads. • The stability of current 50ppm/h (standard) or 10ppm/h (high stable type) are optional. • Output power between 0.5kW and 15kW is optional • Output current between10A and 120A is optional...

Dexing Magnet Tech. Co., LimitedIV. Specification Parameters Item

Dexing Magnet Tech. Co., Limited Remark 1 The source effect refers to the relative change amount for outputting current in full scale when the input AC voltage is fluctuated by 10%. The load effect refers to the relative change amount for the output current when the load is slowly changed by 50% under the condign of the output full load. The source effect and load effect shall be far smaller than the current stability, which falls into oblivion of the current fluctuation. The current stability refers to the relative change amount when the current on the condition of current is in full load output,...
