Main Features
Switching capability : 16A Maximum Surge voltage (between coil and contacts):6kV Thermal class F: standard type (at 85 ) Product in accordance to IEC 60335-1 available 1 From A configurations available Wash tight and flux proofed types available Transient peak current : 44A (at starting) Environmental friendly product (RoHS compliant) Outline Dimensions on bottom (46.0mmX33.0mm)
Description and application These DC zero crossing relay, ZCR16D_1A_V10, contains handouk electronic’s metal contact-protection function, so life time is several times longer than normal relay and its surge on state current at start mode is around 44A, and switching noise at start and switching mode is ultimately limited in switching mode. This is well suitable for high stressing load such as DC motor control which is applied to relay at the starting mode or every switching cycles.
