Specifications

MODELS 7225AC, 7425AC
LINE-POWERED AC BRUSHLESS SERVO AMPLIFIERS
WITH +/-10V ANALOG U-V INPUTS
PROTECTIVE FEATURES
Short circuit (output to output, output to ground) Latches unit OFF (Power off/on, or ground at /Reset input resets)
OverTemperature Latches unit OFF at 70°C on heatplate (Power off/on, or ground at /Reset input resets)
Wire /Reset input to ground for automatic reset after latching fault
Undervoltage Shutdown at internal DC buss < 45VDC
Overvoltage Shutdown at internal DC buss > 195VDC (Model 7225AC), or internal DC buss > 390VDC (Model 7425AC)
(Amplifier operation resumes when internal DC buss is NOT Undervoltage or NOT Overvoltage )
Current-limiting Output current set by header component or external voltage or resistance
Current will fold-back to continuous rated current (10 A) after 2s maximum at 20 A
Relative amplitude of U/V/W phase currents maintained for no loss of commutation
AMPLIFIER DISSIPATION
Watts minimum 17W (Model 7225AC) 7W (Model 7425AC)
Watts @ continuous current 60W (Model 7225AC) 61W (Model 7425AC)
