ZKA-1 SCR Voltage Regulator 

ZKA-1 SCR Voltage Regulator 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. 2.2 When 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 t…
