Product description

MGY1000D is a programmable DC standard source specially designed for the calibration of high-current DC clamp meters, shunts, DC sensors and high-current DC standard meters. This large current source adopts a modular design concept and comprehensively applies advanced technologies such as advanced resonant soft switching technology, synchronous rectification technology, and servo power amplifier technology to minimize the power consumption of internal devices, improve the output efficiency of the entire machine, and reduce the size and weight of the equipment. . The current output between each module is independent and can be superimposed in parallel at will. Each module has independent and complete overload and open circuit protection functions. Multiple machines can be combined in parallel to output 1000A, 2000A, 3000A, 5000A or even 10KA.
This product is small in size, light in weight, wide in range, small in ripple, and has stable output. It has an independent current output port of 20A and below, which facilitates the verification of small current clamp meters; it can be equipped with a small voltage measurement function to support shunt verification. The output current range of a single machine is 1mA～550A. Relevant functions and technical parameters are as follows:

1. Current output range 1mA～1100A;
2. Range: 20mA, 200mA, 2A, 20A, 50A, 100A, 200A, 500A, 1000A;
3. Adjust the fineness to 50ppm;
4. It has open circuit and overload protection prompt function;
5. See the table below for other detailed indicators.
