The 40-310/320 Range of High Voltage Switching Modules will hot switch up to 750V peak and cold switch up to 1000V peak in either general purpose relay (40-310) or multiplexer (40-320) configurations.
These modules contain high quality reed relays with switching ratings comfortably higher than the 40-310/320 specification.
Applications for the 40-310/320 series modules include; circuit board isolation testing, relay testing, semiconductor breakdown monitoring and cable harness insulation testing.
