Product overview

The HD series is a panel-mount DC solid state relay family covering HD75D120, HD100D120 and HD200D40. It provides 4-32VDC control input with 75VDC/120A, 100VDC/120A and 200VDC/40A DC load output capability. MOSFET or SiC MOS output devices, 4000Vrms input-output isolation, anti-rotation terminals and baseplate heat dissipation support testing equipment, X-ray inspection systems, freeze dryers, engineering machinery and industrial DC load control.
