HH Constant Current and Current Limiting Constant Voltage and Pressure Limiting Control Unit

　　

Product characteristics：

　　l      HT constant current and constant voltage control unit: suitable for variable load. Linear heating, uninterrupted, non-flickering.

　　l      Fully automatic closed-loop control, with constant current, constant voltage, current limiting, voltage limiting functions.

　　l      The working status of the power regulator is shown by several indicator lights in the panel, and the failure reason of the power regulator is judged by observing the indicator status, which is convenient for maintenance.

　　l      The whole series is equipped with fast fuse and overheating stop output protection switch to protect the power regulator.

　　l      PC control board adopts patch production and separate control mode, with high voltage, high current resistance, maintainability and no interference.

　　l      Including slow start function, effectively cope with rapid changes.

　　l      Using SCR original, the proportional linear output is stable and the control precision is high.

　　l      Has the function of over-temperature stop output and indication.

　　l      The wiring is simple, easy to install, disassemble and move.
