BPH is a power supply module designed for the UDM35 modular digital panel meter system manufactured by Carlo Gavazzi. It provides regulated power to the instrument across a wide input voltage range of 90 to 260V AC/DC, with a fuse rating of 630mA at 250V (5x20mm). The module integrates seamlessly into the UDM35's modular architecture, occupying the dedicated power supply slot (Slot D) and featuring an LED indicator for operational status. BPH is ideal for industrial measurement and control applications requiring robust power delivery across standard mains voltage ranges, complementing the UDM35's comprehensive measurement capabilities for current, voltage, temperature, resistance, and frequency monitoring.
