The Bosch Rexroth R911283373 (HVE04.2-W075) power supply unit provides an unregulated DC bus voltage to connected drive controllers. It's designed for use with up to three drive controllers and includes an integrated contactor for power shut-down. Compact in design, it offers power dependent on voltage and tolerates humidity up to 95%. For every millifarad of auxiliary capacitance attached to 3 x 400VAC, it can store 144W energy. The device is equipped for three additional capacitance modules with a preference for placement near high-performing drive controllers. The unit requires a control cabinet with air circulation and measures a width of 250mm. It delivers a steady 90kW DC bus power, a 270kW peak for 0.3 seconds, and a short-term 180kW when utilized with a GLD20 DC bus choke under 3 x 480VAC mains supply. The power unit mandates a specific manufacturer cable for control voltage bus connection and has a 160A maxi-mum fuse for the main power section. With a warranty of one year, this product is available for global shipping.
