Product Introduction
DPW high-frequency isolated DC power supply is a high-efficiency DC constant voltage, constant current and constant power power supply that uses a new generation ARM 32-bit processor as the main control chip, PWM pulse width modulation, IGBT as the main power regulation control element, medium and high frequency transformers for input and output isolation, and fast recovery diodes as rectification units.
Working principle
DPW high-frequency isolated DC power supply works from AC-DC-medium and high frequency AC-DC. The power supply is small in size, energy-saving and efficient. It is a new generation of high-frequency isolated DC power supply and an alternative to SCR thyristor DC power supply.
Product Features
1.Automatic switching of constant voltage, constant current and constant power;
2.Fast dynamic response and stabilization speed;
3.High precision and small output ripple;
4.External battery pack for backup use, with charge and discharge management function;
5.Complete protection functions, overload, overvoltage, overcurrent, overtemperature, undervoltage, short circuit, etc.;
6.LCD parameter display, set value and actual value are displayed at the same time;
7.RS485 communication interface, standard MODBUS-RTU protocol, can be converted to any other protocol.

Application
DPW series DC power supplies are used in solar energy, electric vehicles, lithium batteries, and components such as circuit breakers, contactors, fuses, and laboratories/certification units. They are suitable for electrical tests that require high voltage or high current, and provide clients with various test simulations and product aging production tests in the early stages of product design and development. Such as: circuit breaker trip test, other low-voltage electrical instantaneous test, current cycle impact test, reliability test, temperature rise test, rated connection, short circuit connection, and action characteristic test.
