The Dahua DH-PFM344D-4CH-BS is a compact 4-channel CCTV switching power supply that delivers stable DC 12 V output with adjustable voltage levels to support multiple cameras or devices simultaneously. It features overcurrent, overvoltage, short-circuit, and surge protection, a V-0 fireproof casing, and a wall-mount design, making it ideal for reliable power distribution in multi-camera surveillance setups
The Dahua DH-PFM344D-4CH-BS is a premium 4-channel CCTV switching power supply designed to reliably power multiple security devices such as surveillance cameras simultaneously. Built with a compact gray V-0 fireproof shell and CE certification, this unit delivers high efficiency (≥86.95 %) and low idle consumption (≤0.1 W), making it energy-efficient and suitable for continuous security installations. It accepts a wide input voltage range of 185 VAC–240 VAC, and its output voltage can be adjusted to three levels — 12 VDC (Normal), 13.5 VDC (Long), and 15 VDC (Ex-Long) — allowing compatibility with a range of cameras and devices with varying cable lengths and power requirements. Each of the four channels can deliver up to 12 W, with a total capacity of 30 W, and is protected against overcurrent, overvoltage, and short circuits. Enhanced surge protection (±4 kV common mode and ±2 kV differential mode) and static discharge protection (up to ±8 kV air discharge) help safeguard connected equipment from electrical anomalies. Designed for wall-mount installation, this power supply is ideal for small to medium CCTV systems in homes, offices, retail spaces, or commercial environments where multiple cameras must be powered from a single, organized unit.
Multi-Channel Power Delivery: Supplies stable DC power through 4 independent channels, ideal for multi-camera installations.
Adjustable Output Voltage: Supports 12 V/13.5 V/15 V output to match different camera power needs and cable runs.
Total Power: 30 W total output (12 W per channel).
Built-In Protection: Comprehensive safeguards including overcurrent, overvoltage, short-circuit protection, and surge/ESD protection for connected devices.
Efficient & Safe: High efficiency, low idle power use, V-0 fireproof casing, and CE certification for long-term reliability.
Compact & Easy Installation: Wall-mount design with compact footprint, suitable for cabinets, racks, or security junction boxes.
Operating Environment: Works safely in 0 °C to +40 °C ambient temperature.
