AC Input Schemes (continued)
GPS 4830:GP100 Rectifiers(48V, 100A)
GP100 series rectifier input and output voltages are as shown below.
Input Rectifier Output
380 - 480Vac, 3-phase, 50/60 Hz GP100 series
208 - 240Vac, 3-phase, 50/60 Hz GP100 series
48Vdc / 100A
The GPS 4830 system supports three AC schemes:
· Single bulk 3-wire (3-phase): The panel is factory-equipped to distribute the appropriate connec-
tions to the rectifiers through circuit breakers. One circuit breaker feeds two rectifiers (A suffix);
one circuit breaker feeds four rectifiers (B suffix).
· Multiple bulk 3-wire (3-phase): The panel is factory-equipped to distribute the appropriate connec-
tions to the rectifiers through circuit breakers. One circuit breaker feeds two rectifiers (A suffix);
one circuit breaker feeds four rectifiers (B suffix).
· Multiple 3-wire (3-phase): Connected directly to the terminal strips, which then, distribute the ac
power to the rectifiers. One feed for two rectifiers (A suffix); one feed for four rectifiers (B suffix);
of one feed per rectifier (C suffix).
External circuit overload protection, must be provided by customer.
Note: All wire sizes are based on the US National Electric Code.
GPS 4827: NE050AC48TEZ Rectifiers(48V, 50A) and NE075AC48TEZ Rectifier
(48V, 75A)
Infinity NE series rectifier input and output voltages are as shown below.
Input Rectifier Output
208-277Vac, 1-phase, 50/60 Hz NE050AC48ATEZ 48Vdc / 50A
208-277Vac, 1-phase, 50/60 Hz NE075AC48ATEZ 48Vdc / 75A
The GPS 4827 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 2-wire (1-phase): Connected directly to the terminal strips, which then, distribute the ac
power to the rectifiers. One feed for one, two, or three rectifiers. External circuit overload
protection, must be provided by customer.
