LDR40MH12-HT

Product catalog summary

General Overview: The LDR40MH12-HT is a DC power supply with an integrated accupack, designed for uninterrupted power supply (DC-USV) applications. It is suitable for a wide range of input voltages and frequencies, making it versatile for various environments.

Input Specifications: The device accepts AC input voltages ranging from 85 to 270V (0-400Hz) and DC input voltages from 120 to 400V. It has a maximum input current of 1.3A at 115V and 0.65A at 230V, with a peak current of less than 17A at 230VAC. A transient voltage suppressor varistor is included for protection.

Output Specifications: The power supply provides a nominal output voltage of 12 VDC with a current of 8.0A. It features current limiting and a power output of 96 Watts, with a residual ripple of less than 25mVPP. The buffered voltage ranges from 9.8 to 13.0 V following the accu-voltage DC.

Control and Operating Data: The device maintains control deviations of less than 200mV with load variations between 10% and 90%, and less than 25mV with load variations of ±10%. It has a control time of less than 10ms for load variations. The typical buffered time is 30 minutes with a capacity of 6.0 Ah at 20°C. It operates efficiently at approximately 86% in grid mode and can function in temperatures ranging from -20°C to +70°C.

Safety and Protection: The power supply includes slow blow fuses for input and output, and is short circuit proof. It meets various safety standards, including VDE and IEC, and has a high voltage resistance of 4.4kV. It is protected against overload and has an IP65 protection class for the enclosure.

Mechanical and Construction Data: The device measures 83mm x 161mm x 160.5mm and weighs approximately 3.5kg. It can be mounted on a DIN-rail or wall. It complies with multiple construction regulations, including CSA/UL and VDE standards.

Additional Features: The power supply includes status indicators and interfaces for monitoring input, charging, buffer mode, and temperature. It is equipped with a NiMH battery type and provides signals for relay input and accu-protection.
