ZK-01/03 Zero-Cross Triggered SCR Power Regulator

I. Overview: Based on the magnitude of the input signal, this instrument changes the average heating power within a unit time (cycle time) by increasing or decreasing the number of complete power waveforms on the load within the unit time. Since the SCR conducts slightly after the grid voltage crosses zero, both switching loss and RF interference are small. It features strong versatility, wide adaptability, easy installation and reliable operation.

II. Features: 1. Anode-driven SCR, capable of triggering single and bidirectional SCRs in the 10A-1000A range, adapting to various connection methods; widely applicable to high-precision automatic furnace temperature control of various electric heating furnaces. 2. A wide choice of panel dimensions, easy to coordinate with other instruments on the control panel. 3. Using the power zero-cross signal as the reference, the average heating power within a unit time (cycle time) is changed by increasing or decreasing the number of complete power waveforms on the load within the unit time, with small switching loss and RF interference.
