Solid-State Power Controller User’s Manual DIN-A-MITE Solid-State Power Controller Please consult this user’s manual when you place your new DIN-A-MITE into service. It contains all the necessary information to mount and wire the product into the application. This manual also contains all user-pertinent specifications and semiconductor fusing recommendations. Refer to national and local electrical code safety guidelines whenever you install electrical equipment. A-MITE is electrically touch-safe, and includes DIN rail or standard back panel mounting. An optional shorted SCR (silicon controlled rectifier) alarm feature is available on specific models. UL® 508-listed, C-UL® and CE with filter. The DIN-A-MITE solid-state power controller is designed and manufactured by Watlow in Winona, Minnesota. This DIN-A-MITE product is capable of switching up to 40 amps single-phase; 33 amps 3-phase, 2-leg; and 22 amps 3-phase, 3-leg at 600VÅ (ac). (See the output rating curve in the specifications section of this manual.)

1. Push the unit in and down to catch the rail hook on top of the rail. 1. Press down on the release tab while rotating the unit up and away from the rail. 2. Rotate the bottom of the unit in toward the rail. 3. The rail clasp will audibly “snap” into place. If the DIN-A-MITE does not snap into place, check to see if the rail is bent. 4. Mount the cooling fins vertically.

Ungrounded Delta or Wye Load 3-phase, 2-leg DIN-A-MITE Non-latching Alarm Option (models DB_ _ - _ _ _ _ - S _ _ _ ) Shorted SCR (silicon-controlled rectifier) Alarm Non-latching Operation The shorted SCR detector compares the input command signal and actual load current. If load current is present without an input signal then the shorted SCR alarm will energize the alarm triac output. This is a non-latching alarm. This output can be used to drive various indication devices, such as a coil, light, buzzer, etc. See the alternative latching circuit section below. High-limit Contactor (CR1) Semiconductor...
