Additional Information

TeSys U additional function module to be inserted in advanced power bases LUB120, LUB320, LUB380 for motor load monitoring. It provides a 4-20mA output signal, image of the load ratio, to be connected to a load impedance 100 Ohm typical (500 Ohm max). It measures the phase currents and computes the ratio I average/Ir ratio within the range of 0 to 2 for LUCB and LUCD, and of 0 to 3 for LUCC control units. It requires an external power supply 24V DC. To be inserted in the cavity of a power base provided for the auxiliary modules. Certified when used in conjunction with a LUB power base (IEC, UL, CSA, CCC, EAC, Marine), Green Premium compliant (RoHS/REACh).
