Protection Module on Semi-Hermetic Compressor

Check out my new YouTube video on semi-hermetic protection modules.

This is the Lodam SEB1 (signal evaluation basic) used on Bitzer semi-hermetic compressor. Here we have created a simulation rig to show how it detects  motor overheating. The compressor uses embedded PTC thermistors in the stator. With up to 9 in series , anyone can create an overload condition using a series looped total resistance signature  R1+R2+R3 etc until the trigger resistance (equivalent temperature)  is reached.

The simulation unit uses a 10K ohm variable resistor to represent an overheating compressor.
These devices are so very important, and save many compressors.

Yes the vid is a bit shaky, hand filmed , low budget on the mobile.
