- Functional Features:
- Universal AC/DC input voltage range (85-265 V AC / 120-370 V DC) supports global industrial electrical systems and DC power grids (solar, battery-backed), eliminating the need for voltage selection
- High efficiency (>92%) reduces energy consumption and heat generation in control cabinets, reducing the need for additional cooling and extending the service life of adjacent components
- Low output ripple and noise (<50 mV p-p) ensures the stable operation of sensitive electronic equipment (PLCs, HMIs, communication modules) with no signal interference
- Comprehensive auto-recovery protection features (OVP/OCP/SCP/OTP) prevent damage to the power supply and connected equipment from electrical faults, with automatic restart after fault clearance
- Metal housing provides excellent heat dissipation and mechanical protection, ensuring reliable operation in high-temperature control cabinets and harsh industrial environments
- ±10% output voltage trim enables fine tuning of the 24 V DC output, compensating for cable voltage drop in long wiring runs to field devices
- High power factor (>0.95) reduces harmonic distortion of the power grid, complying with industrial EMC standards and reducing the need for additional power factor correction equipment
- Compact 60 mm width allows high-density mounting on DIN rails, saving valuable control cabinet space for large-scale automation systems
- Tool-free DIN-rail clip-on installation enables quick on-site setup and replacement, reducing installation and maintenance time
- Visible LED status indicators (power/fault) provide instant visual feedback on the power supply status, simplifying fault diagnosis
- Input surge protection withstands electrical surges and transients common in industrial power grids, preventing module damage from voltage spikes
- Continuous 24/7 operation design with industrial-grade components ensures high reliability for mission-critical automation systems
- Complies with international safety and EMC standards (CE, UL, IEC), enabling global use in industrial and commercial applications
