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

Features

• Intelligent Battery Management for Extended Service Life - The CliQ M DC-UPS range incorporates advanced charge control and temperature-based supervision that help maximise the lifespan of connected sealed lead-acid batteries. Each model monitors battery conditions continuously, adjusting charge current automatically when input voltage falls below 24 V, and halting charging entirely when temperatures move outside the recommended thresholds. This level of intelligence reduces stress on the battery across changing environmental conditions and ensures stable readiness for backup events. Protection against deep discharge at approximately 21 V further prevents irreversible battery damage, making the system more resilient during extended outages.
• Power Continuity During Input Loss - All models in the series are engineered to deliver uninterrupted 24 V power during supply interruptions, ensuring that critical automation, signalling, telemetry, and communication loads continue operating without reset or data loss. When the DC input drops away, the UPS transitions smoothly into battery mode with output delivered at Vbattery minus 0.5 V. This seamless handover, free from switching delays or output instability, is critical for equipment that must remain continuously energised, particularly in remote or unmanned installations.
• High Inrush Handling Through Short-Duration Power Boost - A defining capability of the 10 A, 20 A, and 40 A variants is their built-in short-term power boost function, which provides 150 percent of rated output for up to seven seconds. This allows each UPS to absorb inrush currents associated with motors, solenoids, relays, and other inductive loads without nuisance shutdowns. The ability to withstand momentary surges helps reduce system design constraints and ensures a more stable startup profile for connected equipment, even under fluctuating load conditions.
• Comprehensive Diagnostics Through Relay Contacts and LED Indicators - Maintenance teams benefit from immediate insight into system status through clearly defined relay outputs and diagnostic LEDs. The UPS communicates key states such as Battery Ready, Buffering, and Replace Battery, while LED indicators provide real-time feedback on charge level, fault conditions, polarity issues, and temperature warnings. These diagnostics enable rapid fault identification, simplify commissioning, and provide valuable integration points for remote monitoring systems such as PLCs, RTUs, SCADA platforms, and building management systems.
• Robust Electrical and Environmental Protection for Demanding Sites - Each model in the CliQ M range includes a suite of protective mechanisms designed to safeguard both the UPS and downstream equipment. This includes reverse polarity protection on the battery terminals, incorrect battery voltage detection up to 30 V, overvoltage shutdown on the input side, and automatic recovery once normal conditions return. Temperature-driven shutdown prevents overheating during prolonged high-load operation, while vibration and shock ratings defined in the datasheet ensure stable performance in industrial environments. Together, these protections support long-term reliability in harsh, high-duty applications.
• Compact DIN Rail Design That Simplifies Panel Integration - The unified mechanical design across the 10 A and 20 A models, and the slightly wider footprint of the 40 A variant, ensures easy installation within new and existing control cabinets. All units mount on standard TS35 DIN rail and require minimal clearance for natural convection cooling, making them well-suited to modern panel layouts where space is at a premium. With no active cooling elements and minimal service requirements, the UPS modules provide a low-maintenance backup solution that supports clean cable routing, straightforward commissioning, and long-term operational stability.
