Optimized standard configurations matching Russian substation standards (220VDC / 110VDC input with isolated 48VDC outputs)
The Moscow municipal territory and surrounding industrial clusters are experiencing rapid electrification upgrades. Key entities, including transit operators like the Moscow Metro (Moskovsky Metropoliten) and massive regional telecom operators, are transitioning toward modern smart grid automation. In high-voltage environments, direct current (DC) distribution is preferred to bypass phase matching issues and guarantee battery backup system direct integration.
However, substation control loops and data processing systems commonly utilize a standardized 48VDC input voltage. Therefore, stepping down 220VDC or 110VDC using highly isolated, low-noise converters is a critical requirement. Our 19-inch 2U rack-mounted solutions are designed specifically for this role, maintaining operational integrity during fluctuations, thermal extremes, and electromagnetic interference.
Unlike standard commercial grade power electronics, industrial equipment in Central Russia must withstand vast temperature drops and seasonal variance. Indoor equipment rooms may not always be temperature-controlled during maintenance. Wemaxpower converters are engineered with industrial-grade silicon semiconductors, customized aluminum heat-sink profiles, and active temperature sensor circuits.
These components allow cold start operations from -40°C up to +70°C without structural failure. High-quality fans with automatic speed adjustment depending on external load thresholds ensure long operational lifetimes (MTBF > 150,000 hours), decreasing onsite maintenance requirements for remote locations.

Standardized 19-inch equipment racks allow modular component stacking in telecom and power transmission rooms. The choice of a 2U height represents an optimal balance between structural rigidity, cooling channel space, and current density. While 1U profiles struggle with airflow restriction and thermal density when power output exceeds 1.5kW, the 2U frame allows for heavy copper transformers, high-inductance filter chokes, and large electrolytic capacitors that ensure ultra-low output ripple.

Get Technical ConsultationDeploying energy equipment within the Russian Federation requires strict adherence to Technical Regulations of the Customs Union (TR CU). Key requirements include TR CU 004/2011 (Safety of Low-Voltage Equipment) and TR CU 020/2011 (Electromagnetic Compatibility of Technical Products).
Wemaxpower's DC-DC converters are engineered with EMI filter blocks that limit feedback harmonics on input power lines. This design prevents electrical noise from affecting neighboring telecommunication rectifiers. The isolation design meets the dielectric strength requirements of industrial substations, providing reliable performance in these demanding environments.
