B&R 8B0C0320HC00.00A-1 Auxiliary Power Supply

ACOPOSmulti auxiliary power supply module 8B0C0320HC00.00A-1 from B&R is the high‑current 24 V auxiliary rail for ACOPOSmulti drives, designed to power control electronics and connected devices within HV DC bus systems. It accepts a 24 VDC external source on 24 VIn and provides two 24 V outputs: a primary 24 VOut rated up to 32 A continuous in normal operation (30 A in supply mode) and a secondary 24 V output rated at 5 A for auxiliary circuitry. The module connects to a nominal 750 VDC DC bus and supports an operating range of 260–800 VDC, with full continuous power available from 315 to 800 VDC. The 24 VOut regulation is 25 VDC × (U_DC/315) when the HV bus is 260–315 V, and 24 VDC ±6% when the bus is 315–800 VDC, with a typical ripple around 50 mV. The internal 25 VDC system supply can deliver up to 42 A peak for under 4 seconds and provides protections for no‑load, overload, short circuit, and overtemperature, with SELV/PELV isolation. The unit uses cold plate or pass‑through mounting and carries CE, UKCA, UL (cULus E225616), and KC certifications. It includes input for an external 24 VDC source and outputs to power external 24 V devices while feeding the drive’s internal electronics in ACOPOSmulti configurations. Material number 8B0C0320HC00.00A-1.
