China KD Series Silicon Controlled Rectifier Power Supply - Leading Suppliers & Factory for Reliable Performance
Product Feature
It can be used: indoors, without corrosive gas, flammable gas, dust and explosive gas.
The transformer adopts three-phase five-column structure and six double reversed start rectifying circuits without balanced reactor, saving electricity about 10%.
The secondary side silicon controlled rectifier is adopted for voltage regulation.
The main transformer adopts bridge rectifier structure, which can ensure the whole machine to run at 100% full load for 24 hours continuously and has certain overload capacity.
The main control board adopts a full set of technology imported from Japan's SanRex, and has a high anti-interference trigger control system with strong anti-interference ability.
High control precision, good stability and reliable operation.
Perfect control and protection function: such as soft start, stabilized voltage/stabilized current as well as overheating, overcurrent, short circuit and default phase, etc.
RS485 interface or standard 4-20mA, 0-20mA, o-10V and 0-5V computer signals can be provided.
The power supply has the functions of manual operation and automatic control.
Manual operation is touch screen operation, and the touch screen is installed on the control box. Relevant parameters such as current, voltage, working time and working curve can be preset on the touch screen and can be monitored.
Configure the remote control cable from the rectifier to the tank edge, and the length of the remote control cable for a single rectifier is 15m.
The material of the remote control box is made of ABS flame retardant and high temperature resistant materials, so as to prevent fire and corrosion.
Provide RS485 communication interface , communication protocol: MODBUS RTU.
