1. Introduction
ZK type SCR voltage regulator is used with SCR, it can adjust the load heating power, phase-shifting triggering mode have depth voltage negative feedback, so it has a good adjustment linear, the impact of network fluctuating will be the smallest. Zero-crossing triggering mode's instrument design have network voltage fluctuation compensation function, it can stabilize different power voltage heating power
2. Characteristics
2.1 Design newly,on the plane built-in big ammeter is for output indication, legible to read and adjust the machine to zero. The instrument's depth cut normal production down to half than, weight lighten 2kg, shock-resistant feature is good,anti-jamming ability is strong.
2.2When load is short circuit or overcurrent,the instrument can close automatically SCR's trigger signal in 1~2 period,let SCR carry current and protect from damage,at the same time it have indication function when load is short circuit.
2.3Directly get synchronizing signals from the network, applies to the " Y " method connection, control is stable and reliable.
