Watlow DIN-A-MITE and ASPYRE solid-state power controllers for electric heat, from 12 to 800 amps.
Power controls go by many names: solid-state relays (SSRs), SCRs, silicon rectifiers, thyristors, zero-cross relays, triac relays and phase-angle SCRs.
A silicon controlled rectifier (SCR) power controller is a low-cost, compact and versatile solid-state option for controlling electric heat. The Watlow family of DIN-A-MITE and ASPYRE SCRs can fit almost any heating system requirement.
Is the heater load single-phase or three-phase, and does the controller need to switch two legs or all three?
Know the full-load amps of the heater bank. Current ratings run from 12 to 800A depending on model.
SSR, SCR and DIN-A-MITE basics.
Both switch heater power with no moving parts. The terms overlap; SCR power controllers such as
DIN-A-MITE and ASPYRE add higher current ratings, multi-phase configurations and control options.
That depends on your load current, phase and control input. Browse by series above, or send us your heater and controller details and we’ll recommend one.
DIN-A-MITE manuals are in our Manuals & Downloads library.
