Characteristic

1regulator adopts a built-in level meter for large output instructions, easy to read and mechanical zero. Installation depth than the old product is shortened by half, weight three times, shock resistance performance,

Strong anti interference capability.

2if necessary, to enable fast thyristor over-current protection function, the load short circuit or overcurrent, the regulator can be in 0seconds automatically shut down the trigger signal of the controlled silicon, the silicon controlled interception

Flow from damage, while having a load short circuit indication function, short circuit protection values from the user external current transformer (optional ) decision.

3 direct from the grid and zero crossing signal, applied to the" delta" type," Y" shape and other load wiring method, the grid frequency requirements low, stable and reliable control

4 on cold resistance of low load, can be used to manually for soft start.

5" feedback" quantity adjustment potentiometer is arranged in the panel, professionals may be considered as" output limiting" use, quality and safety factor can obtain upgrade.

In particular: the regulator power supply shall be controlled by the load of the electric one one correspondence, or from the two party power phase inconsistency caused the load voltage constant or not fully opened

Issues such as.

Main technical index

The 1 input signal:0～ 10mA ( input impedance 800 ohms ); from 4 to 20mA ( input impedance 250 ohms )

2: the amplitude of output pulse width≥ 3V,≥ 40 μ s (20 Ωload)3 Maximum conduction angle : 150°

A 4 over-current protection current ( special order ): by the external current transformer specifications decision ( without current transformer without over-current protection function)

5meter: default working power supply for AC 220V± 15%3VA;50Hz ±1Hz AC380V power supply must be in order that
