To get 400Vdc from 3-phase 208Vac, you need a multi-stage rectifier that includes a system for voltage step-up and potentially isolation, followed by a three-phase bridge rectifier to convert the AC to pulsating DC, which is then smoothed by filter capacitors to produce the 400Vdc. For a more compac Read More

The core difference between Modbus protocol and CAN protocol lies in their design positioning: Modbus is an application layer protocol for industrial equipment data exchange, relying on underlying buses such as RS485 and TCP; CAN is a bottom layer (physical+data link layer) protocol that balances da Read More

The three phase Static Transfer Switch is the second option automatic switching system of the power supply. Under the normal working state, the main power supply is within the normal voltage range, and the load is always connected to the main power supply. When the main power supply fails, the load Read More

As a key equipment in the power system, GZDW DC Power Supply Cabinet are mainly used for DC transmission, regulation, and protection. Their stable operation relies on the collaborative work of multiple internal modules, among which Diode Drop Units play a crucial role. Diode Drop Units, composed of Read More

The three phase Static Transfer Switch is the second option automatic switching system of the power supply. Under the normal working state, the main power supply is within the normal voltage range, and the load is always connected to the main power supply.

Single phase Static transfer switch can only work normally in parallel when the frequency and amplitude of two AC power sources are the same single phase 110Vac or 220Vac. When a fault occurs in one of the AC power sources, a balanced current will be generated between the two power sources, causing Read More
