Guardian 5-7U M38
Guardian Access M38 is a 5-7RU high 19” rack-mounted, integrated 600 Amp DC power system providing an output of -48VDC. These highly configurable systems incorporate 3 rectifier shelves with up to 11 Guardian family high efficiency hot-swap rectifiers.
Guardian Access M38 provides a maximum total current of 600A (N+1). This may be shared between the load and battery charge current, the latter being programmable via the controller. The rectifiers are internally fan cooled with speed control which is a function of load and temperature, keeping acoustic noise to a minimum. The DC distribution module in Guardian Access M38 can accommodate up to 20 pluggable breakers or TPS fuse modules. 4 or 8 of these in each case may be connected to the bus via the Low Voltage Battery Disconnect (LVBD).
