The Slimline Plant belongs to the Delta MidD
product series. This high power-density system is
ideal for space critical applications. An integrated
modular system allows flexible and adaptable
installations.
The 2U rectifier shelf building blocks contain slots for
6 rectifiers. Each 2U block can provide 300 amps of
charge in either standard 92% efficiency Slimline rectifiers or 96% efficiency rectifiers. Up to two 2U
shelves can be used to provide up to 600 amps of
capacity at –48 volts.
Modular distribution panels provide up to 26 positions
per panel for load and battery circuit breakers. Up to
3 distribution panels can be used for distribution capacity of 78 bullet style circuit breakers. Distribution
rails are tiered for easy distribution cable management.
