AC Input Schemes
595 Rectifiers (48V,
200A) and 595LT
Rectifiers (48V,
220A)
595 and 595LT series rectifier input and output voltages are as shown
below.

Input Rectifier Output
380-480Vac, 3-phase, 50/60 Hz 595A and 595LTA series
48Vdc
200-240Vac, 3-phase, 50/60 Hz 595B and 595LTB series
The system supports three ac schemes:
• Single bulk 3-wire (3-phase): The panel is factory equipped to
distribute the appropriate connections to the rectifiers through
circuit breakers.
• Multiple bulk 3-wire (3-phase): The panel is factory equipped to
distribute the appropriate connections to the rectifiers through
circuit breakers.
• Multiple 3-wire (3-phase): Connected directly to the terminal strips,
which then distribute the ac power to the rectifiers. One feed for
each rectifier, external circuit overload protection, must be
provided by customer.
596 Rectifiers (24V,
100A/125A and
48V, 50A/100A)
596 series rectifier input and output voltages are as shown below. 
Input Rectifier Output
176-264Vac, 1-phase, 50/60 Hz
596A and D series 48Vdc
596B series 24Vdc
The ac power may be phase-to-phase or phase-to-neutral, as long as the
correct voltage range is provided to the rectifier.
The system supports two ac input schemes:
• A single bulk 3-wire (3-phase) or 4-wire (3-phase + neutral) can be
brought into the ac panel located in the cabinet. The panel is factory
equipped to have either a phase-to-phase or phase-to-neutral
distribution to each rectifier through a two-pole ac circuit breaker.
Jumpers can be ordered to field modify the phase-to-phase panel to
have a phase-to-neutral distribution to each rectifier through a
two-pole ac circuit breaker.
