General Overview: The LDR40MH12-HT is a DC power supply with an integrated accupack, designed for uninterrupted power supply (DC-USV) applications. It is identified by the FEAS order number 589933.

Input Specifications: The device accepts an AC input voltage range of 85 - 270V (0-400Hz) and a DC input voltage range of 120 - 400V. The input current at nominal load is 1.3A at 115V and 0.65A at 230V, with a peak input current of less than 17A at 230VAC. It includes a transient voltage suppressor varistor for protection.

Output Specifications: The power supply provides an output voltage of 12VDC with a nominal output current of 8.0A. It has a power rating of 96 Watts and a residual ripple of less than 25mVPP. The buffered voltage ranges from 9.0 to 13.0 VDC, following the accu-voltage.

Control Data: The control deviation with load variation is less than 200 mV for 10-90% variation and less than 25 mV for ±10% variation. The control time is less than 10ms for load variation between 10-90%. The typical buffered time is 30 minutes with a capacity of 6.0 Ah at 20°C.

Operating Conditions: The device operates at 100% duty cycle within a temperature range of -40°C to +70°C. It features self-cooling and has an efficiency of approximately 86% in grid mode. The installation altitude is unlimited, and the MTBF is greater than 380,000 hours without the accupack.

Safety and Protection: The power supply includes a 2.5A slow blow fuse for 115V and a 1.25A slow blow fuse for 230V. It is short circuit proof and integrates overload protection. It meets various safety standards, including VDE0570, VDE0806, and EN62368.

Mechanical and Environmental Data: The dimensions are 83mm x 161mm x 160.5mm, and it weighs approximately 3.5kg. It can be mounted on a DIN-rail or wall. The device is IP65 rated for protection class and can withstand vibrations greater than 30g at 33Hz.

Compliance and Standards: The LDR40MH12-HT complies with multiple international standards, including CSA/UL, VDE, IEC, and EN regulations, ensuring its reliability and safety in various applications.

Additional Features: The device includes status indicators for input, charging, buffer mode, and temperature, as well as relay input and accu-protection signals.
