Description

DC-AC Solid State Relays

Product Overview

The SSR series miniature solid state relays adopt a constant current drive circuit typical of relays, with a stable drive current of 5–6mA, ensuring low power consumption and high reliability. Equipped with an optocoupler zero-cross trigger, they feature minimal interference with the power grid and high insulation withstand voltage. The output employs varistors to absorb voltage spikes from the power grid, resulting in low leakage current and long-term reliable operation.

4. Equipped with test and mute functions, operable via panel buttons or external switch connected to terminals.

5. Powered by a universal 100-240VAC input range switching power supply or a 24VDC power supply.

6. Certified under the ISO9001:2000 quality management system, ensuring reliable quality.
