Heavy-Duty Industrial UPS — EP Single-Phase Class for Small Power-System Rooms

Not every industrial UPS room runs three-phase. Many small power-system control rooms, substation protection panels, plant-control cabinets, and DCS panels run single-phase — but they still live in the same harsh environment as the big three-phase halls. The EP single-phase class brings the same heavy-duty industrial engineering as the broader EP family — to the small rooms that need it.

Built for the small industrial rooms that still need heavy-duty engineering

The single-phase class uses the same industrial-grade online double-conversion platform as the broader EP family, engineered for the realities of small power-system rooms. Reinforced mechanical construction, conformal-coated boards, redundant cooling, and a service model designed for plant maintenance teams — at the scale that small control rooms actually need.

Where it makes the difference

• Small substation protection panels and DC rooms with single-phase loads.

• Plant-control cabinets and DCS panels running single-phase protection and SCADA loads.

• Power-distribution automation panels with single-phase provisions.

• Rail-power and traction substation control panels with single-phase loads.

• Energy-management and metering rooms where the UPS lives in a small but harsh cabinet.

What you gain

• An industrial-grade online UPS with IGBT rectification, engineered for single-phase small power-system rooms.

• Reinforced mechanical construction and conformal-coated boards for harsh-environment survival.

• Redundant cooling engineered for high ambient temperatures and dust-laden atmospheres.

• Strong overload capability and the inrush tolerance to start small industrial protection loads.

• Wide input tolerance for the slow, dirty mains events common to industrial sites.

• Comprehensive protection: overload, short-circuit, over-temperature, over-voltage, under-voltage.

• Standard communication interfaces — RS232, RS485, and dry contacts — for plant SCADA integration, with an optional SNMP card.

How the platform works for you

The single-phase class uses a robust industrial-grade online double-conversion power stage with IGBT rectification, designed for the slow, steady behaviour that small industrial control rooms expect from a UPS. The cabinet is engineered for the realities of harsh environments at the smaller scale: reinforced steel, conformal-coated electronics, redundant cooling, and predictable service access. The result is a clean sine output with the inrush tolerance to start small industrial loads — and the robustness to survive the room it lives in.

Service, integration, and lifecycle

The single-phase class is supported by the same global field-engineering network as the rest of the EP family, with regional spares and industrial-trained service teams. Integration with plant SCADA, DCS, and BMS is straightforward via standard interfaces, firmware updates are routine, and the system is engineered for control-board upgradeability across generations.

Frequently Asked Questions

• Why heavy-duty rather than a standard single-phase UPS? Heavy-duty single-phase UPS is engineered for dust, temperature extremes, vibration, and the inrush currents of industrial loads — a standard UPS would not survive.

• Can it start small industrial protection loads? Yes — strong overload capability and inrush tolerance are engineered in.

• What about harsh atmospheres? Reinforced construction, conformal-coated boards, and redundant cooling are engineered for dust, temperature extremes, and conductive pollution.

• What communication options are available? RS232, RS485, dry contacts, and an optional SNMP card.

• Is there a bypass for service? Yes — built-in bypass with manual maintenance bypass for safe service on a live system.

• How is service handled? Regional spares, factory-trained industrial engineers, and predictable maintenance schedules.

• Is it future-proof? Modular firmware and a field-replaceable control board extend useful life across generations.

• What warranty and service options exist? A standard multi-year warranty with extended and on-site plans available globally.

Information Security and Data Protection

Role-based access, audit-friendly event logs, and encrypted remote communication where supported by your plant SCADA or management platform protect operational data. Telemetry stays inside your plant network boundary by design.
