Heavy-Duty Industrial UPS — EP Three-Phase Family for Harsh Industrial Environments

Heavy industry is not a softer version of data-centre IT. The air carries dust and conductive particles. The temperature swings are wide and unforgiving. The loads are heavy motors and process drives that punish a soft power supply. The EP three-phase family is engineered for that world — a robust, transformer-isolated, industrial-grade online UPS platform built for metallurgy, petroleum, chemical processing, electric power, rail transit, and the rooms where a standard data-centre UPS would not survive a quarter.

Built for the rooms that punish standard UPS equipment

The EP family uses industrial-grade online double-conversion topology with IGBT rectification and a robust output stage engineered for heavy industrial loads. The cabinet is built for the realities of harsh environments: reinforced mechanical construction, conformal-coated boards, redundant cooling, and a service model designed for plant maintenance teams rather than data-centre white-space contractors.

Where it makes the difference

• Metallurgy and steel-making process lines where dust, vibration, and temperature swings are routine.

• Petroleum and petrochemical plants with hazardous-area considerations and heavy motor loads.

• Chemical processing facilities running sensitive control and SCADA loads in harsh atmospheres.

• Electric power and grid-protection rooms where galvanic isolation and robustness are the baseline.

• Rail transit, mining, and heavy-engineering operations where the UPS must survive the room.

What you gain

• An industrial-grade online UPS with IGBT rectification and a robust output stage engineered for heavy industrial loads.

• 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 heavy motors and process drives.

• 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 EP family uses a robust industrial-grade online double-conversion power stage with IGBT rectification, designed for the slow, steady behaviour that heavy industry expects from a UPS. The cabinet is engineered for the realities of harsh environments: reinforced steel, conformal-coated electronics, redundant cooling, and predictable service access. The result is a clean sine output with the inrush tolerance to start heavy industrial loads — and the robustness to survive the room it lives in.

Service, integration, and lifecycle

The EP family is supported by a global field-engineering network with regional spares and industrial-trained service teams. It integrates with the leading plant SCADA, DCS, and BMS platforms via Modbus, RS485, and dry contacts, supports remote firmware management, and is designed for module-level upgradeability — so a system installed today can host the smarter control boards and power stages of tomorrow.

Frequently Asked Questions

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

• Can it start heavy motors and process drives? 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.

• Does it provide galvanic isolation? Yes — the platform supports output isolation transformer options for the rooms that require it.

• 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.

• 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.
