Reliable quality with builtin battery charging and UPS functions. The unit provides main and standby power circuit switches, and is suitable for both leadacid and lithiumion batteries. stability and flexible control. ACDC conversion efficiency is 88 percent. CH1 output voltage is adjustable from 20 percent to +5 percent via a voltage regulator. It can detect the state of TTL signals for system integration. Comprehensive protection for safer operation. Operating temperature range is 20C to +60C. Includes short circuit, overload, overvoltage, and overtemperature protections to safeguard connected equipment. Broad compatibility with durable construction. The switching power supply uses a metal casing with natural air cooling. Suitable for fire protection systems and uninterruptible DCUPS systems, among other applications. Practical use scenarios Fire protection or safety systems that require reliable backup power and integrated battery charging with seamless transfer between main and UPS power. DCUPS deployments for critical equipment such as servers, telecom gear, or control panels, ensuring continuous operation during outages. Environments with mixed battery banks (leadacid and lithiumion) needing a single power converter to manage charging and power delivery efficiently.
