What this product is

What this product is

Architecturally, the M500D consists of a central processor mothercard, isolated multichannel ADC front-end conditioning circuits, an ultra-wide input DC-DC power regulation stage, a hardware real-time clock (RTC), and non-volatile flash storage. Connected via robust backplane edge connectors, it interfaces with bus voltage dividers, Hall-effect/shunt current sensors, RTD temp probes, AC power sensors, and contactor driver circuits, strictly compliant with IEC 60950-1, EN 300386, and YD/T 1058 standards.

What problem it solves

This controller mitigates common field vulnerabilities such as battery thermal runaway caused by uncompensated float voltages, rectifier stress disparity due to improper load sharing, service drops resulting from non-tiered Low Voltage Disconnect (LVD) operations, and network blind spots. The M500D provides millisecond-precise float/boost switching, multi-stage LLVD/BLVD isolation, and deep event blackbox logging to prevent catastrophic site blackouts and battery degradation.

Who and where it is for

Engineered for telecom macro base transceiver stations (BTS), edge aggregation centers, dense wavelength division multiplexing (DWDM) optical repeater huts, railway signalling equipment rooms, utility substation DC panels, and enterprise modular edge data centers requiring high-availability -48V DC power monitoring.
