CHAPTER 1: DESCRIPTION, FEATURES AND SPECIFICATIONS
•
Fused regen circuit (shunt regulator) with a 50W internal load resistor bank bleeds off
excess DC Buss voltage when decelerating a large load inertia. Additional regen resistor
can be connected externally.
1.3 Specifications:
This section contains the specifications for the brushless trapezoidal, sine/resolver and
two or three phase input current mode D.C. Servo Amplifiers. These specifications also
include power supplies for the amplifiers.

maximum. Forced air cooling.
1.3.1 Single Amplifier Module (SMA8X05-1):
The amplifier module(s) require an external DC power supply which must include a
bridge rectifier, buss capacitor, solid-state relay and shunt regulator. Forced air cooling is
required to meet the maximum power ratings specified below.
