Bipolar Constant Power Supply

Our company is proud to introduce the DXMP series bipolar constant current power supply. This power supply boasts high stability of output current, and low ripple and noise.

The DXMP series bipolar constant current power supply has been designed to meet the stringent demands of industrial applications, such as semiconductor testing, and laser diode manufacturing. The power supply has a wide input voltage range and it can produce a stable output current from a few milliamperes to several amperes.

The output current stability of the DXMP series bipolar constant current power supply is second to none. This is achieved through a number of innovative features such as advanced output control algorithms and precise sensing of the output current.

One of the outstanding features of the DXMP series bipolar constant current power supply is the exceptionally low ripple and noise levels. This is achieved through the use of advanced filtering techniques and meticulous attention to the design of the power supply.

In addition, the DXMP series bipolar constant current power supply is incredibly easy to use. The user-friendly interface allows you to set and adjust the output current, voltage, and other parameters with ease.

We are confident that the DXMP series bipolar constant current power supply will meet and exceed your expectations. Its high stability of output current, low ripple and noise levels, and ease of use make it an ideal choice for industrial applications.

2.1 The output current of the bipolar constant current output source can continuously vary between positive and negative rated current extremes.

• The current smoothly crosses zero without breakpoints and non-switching commutation;
• Output current and voltage four-quadrant operation (suitable for inductive loads);
• The current change rate can be set in the range of 0.0007~0.3 F.S./s (F.S. is the rated output current extreme value);
• AC input, single-phase 220V±10% (50Hz/60Hz) or three-phase 380V±10% (50Hz/60Hz);
• The output voltage range is 0 - ±200V, the output current range is 0 - ±1000A, and the maximum output power is 200KW.

2.2 High current stability and low ripple.

• Current stability: better than ±50ppm/h (standard type); better than ±5ppm/h (high stability type);
• Current accuracy: ± (0.01% set value + 1mA);
• Current resolution: 20 bit, for example 15A power supply, current resolution is 0.03mA;
• Source effect: ≤ 2.0×10-5 F.S. (output current change when supply voltage changes by 10%);
• Load effect: ≤ 2.0×10-5 F.S. (output current change when load changes by 10%);
• Current ripple (RMS): less than 1mA.

2.3 Two output modes.

• Current mode: directly set the current in the magnet or coil;
• Magnetic field mode: directly set the size of the magnetic field in the magnet or coil;
• Closed loop adjustment mode, constant magnetic field value;
• Note: The magnetic field mode needs to be matched with our company's high-precision Gaussian meter and probe.

2.4 Two modes of operation.

• Local control adopts high-definition touch screen display and operation;
• The remote can be controlled by the computer through RS232 interface, RS485, LAN and USB are optional.

2.5 Multiple protection functions.

• Input power supply power-off protection (when the input power supply is powered off, internal protection absorbs the inductive load back feed energy);
• Overcurrent protection (automatic current reduction, uncontrollable overcurrent will shut down the power output and alarm).
