Electric Heat Sequencer is suited for HVAC/R industry.

Used to stage heaters to prevent circuit overload, ZC series uses positive temperature coefficient and bimetal disc(s) to initiate switching action. Contacts close after specified time range. PTC is self-current limiting, ensuring stable switching action over voltage range. Featuring solid state construction, shock- and vibration-resistant product has operating temperature range of -50 to...

Power Transformers have UL 1585 Class 2, 3 approvals.

AHI series transformers offer dual bobbin non-concentric design that reduces inter-winding capacitance and eliminates need for electrostatic shield. Shroud and bobbin meet UL 94V-0 flammability requirements. Other features include specially designed bobbin wall slots that eliminate wire crossovers, and insulating shroud that provides 4,200 Vrms hi-pot dielectric strength. Units are available in...
