Figure A.1 - Typical Low-volt Motor Armature Current Ratings
NOTE. The armature power bridge circuits in all 590SP models are not equipped with a "free-
wheeling" or fly back rectifier. Accordingly, some motors may require derating, particularly at low
speeds due to the higher current form factor that this type of supply produces. Consult the motor
manufacturer for derating information.
Armature Voltage 380 VDC maximum with 400 VAC input
180 VDC with 230 VAC input
90 VDC with 115 VAC input
Power Loss 90 Watts at 45°C (113°F) ambient at maximum output of 27 Amps DC. Refer
to Figure 3.1 for power dissipations at lower currents.
