Brief description：

SB-PU70E has the function of parameter copying, which is quite useful to set the same parameters on multiple inverters. SB-PU03 is a keypad with a potentiometer, which facilitates the adjustment of the setting.

Prduct Features:

SZ20G series braking units can be worked together with braking resistance in order to absorb the electrical power that is regenerated at motor braking. It can avoid overvoltage of inverter. Besides for Slanvert inverter, SZ20G can also be used in other brand inverters. With its reliable and stable structure, it will be customers’ prime choice.

Technical Specification:

Input voltage：DC300～800V
can working at rated current constantly. Several SZ20G can be used together to increase braking capacity
Braking voltage can be selected and the factory setting is 680V±1.5％.
Faulty relay output: The relay is cut off and the terminal TB-TC is connected when fault occurs. TA-TC terminal connected when no fault occurs.
Complete protective function including over hot protection, over current protection (150% rated current) and overload protection.
