Overview
The Rhino PSB24-240S-3 is a high-efficiency 3-phase switching power supply engineered for demanding industrial automation and control applications. Delivering a stable 24 VDC output at 10A (240W), this unit accepts 480 VAC nominal 3-phase input and is housed in a compact aluminum enclosure with 35mm DIN-rail mounting. The PSB24-240S-3 provides reliable DC power for PLCs, HMIs, sensors, motion drives, and field devices in manufacturing, process control, and distributed automation environments.
Key Features
- Adjustable output voltage (24–28 VDC) via potentiometer for tuning to device requirements
- Wide input range (320–600 VAC 3-phase) enables stable operation across variable or unstable supply conditions
- High efficiency (92% at 400–500 VAC) minimizes heat generation and reduces energy costs
- Integrated protections: overvoltage, overload, and short-circuit protection with internal fuse
- Voltage monitoring support for real-time diagnostics and system stability
- Screw terminal connections enable fast, reliable wiring with flexible or solid cable
