ETC-900E Digital Temperature Controller for Refrigeration and Defrost

ETC-900E Digital Temperature Controller for Refrigeration and Defrost 

Applications and Features:

1. Walk-in coolers and freezers, refrigerated cabinets and displays, glass top freezer, Island freezer ect.

2. For frozen products, it automates the defrost processes according to the need of installation (smart defrost). Its output relay directly controls compressors of up to 2HP and its defrost output has a current capacity of 10A. The ambient temperature control has a normal setpoint and an economic setpoint, apart from the fast freezing function and alarm functions indicating open door. It also features a digital filter, intended to simulate a mass increase in the ambient sensor (S1), thus increasing its response time (thermal inertia) and avoiding unnecessary drives of the compressor. It also includes a smart key, lock system and a control functions shutdown mode.

Specifications:

1. Power supply: 115 or 230VAC±10%, 50/60Hz
