Delta Electronics CliQ M DRU-24VAMN Series DC UPS Module

The Delta Electronics CliQ M DRU-24V AMN DC UPS range provides a reliable and efficient backup solution for maintaining uninterrupted 24 V DC power in industrial, automation, utility, water telemetry, and communication systems. Available in 10 A, 20 A, and 40 A output , the series combines high efficiency, intelligent battery management, and robust electrical protection within a compact, corrosion-resistant aluminium enclosure engineered for long-term field deployment. All models operate from a wide 18–30 V DC input range and deliver stable regulated output at Vout = Vin minus 0.5 V during normal operation, ensuring dependable support for sensitive loads.

Each model features a 150 percent power boost capability for up to seven seconds, allowing the UPS to handle inrush currents and short transient demands without system disruption. When the input supply is lost, the units automatically transition into battery mode, delivering uninterrupted output power at Vbattery minus 0.5 V. Adjustable charging current and selectable buffering time give integrators the flexibility to pair the UPS with a broad range of sealed lead-acid battery capacities, while battery temperature sensing and over-discharge protection help extend battery lifespan and maintain predictable performance. These features, combined with high 98 percent efficiency across the series, support energy-conscious designs and reduce system heating.

The DRU-24V AMN range incorporates clear operational visibility through intuitive LED indicators and dedicated relay contacts for Ready, Buffering, and Replace Battery conditions. This diagnostic structure provides quick status identification during installation, routine inspection, or remote system monitoring. Integrated protections operate continuously, including input undervoltage shutdown, reverse polarity protection, deep discharge protection around 21 V, thermal shutdown when operating conditions exceed recommended limits, and safeguards against incorrect battery voltage. These protective layers enhance system resilience and reduce maintenance intervention across diverse application environments.

Designed for demanding conditions, all models operate reliably across a wide temperature range from –40 °C to 70 °C, with de-rating applied above 60 °C as indicated in the datasheet’s thermal performance guidelines. Long-term reliability is supported by an MTBF rating above 500,000 hours, and installation is simplified through TS35 DIN rail mounting and consistent mechanical design between the 10 A and 20 A models, with a slightly wider form factor for the 40 A variant. With robust electrical performance, intelligent battery control, and a compact form suited to modern control panels, the CliQ M DRU-24V AMN DC UPS series provides a dependable backup solution for maintaining power continuity in any 24 V DC system.
