Product Details

	Power Series SSRs offer a wide variety of voltage (110-575 volts) and current options (3-45 amps). AC series have a built-in snubber and zero-voltage turn-on; transient-proof models are available. DC series offer isolated DC control and are RoHS compliant. Models with LEDs are now available.?
	Z Series SSRs are low-cost, 10 amp SSRs with tool-free quick-connect terminals.

	Printed Circuit Series SSRs mount on circuit boards and control up to 4 amps. MP series have a minimum footprint.
	P series are low profile.
	Heat Sink Series SSRs make installation easier with an integral heatsink.
