Vertiv Liebert APM2 30-600kW 400V Modular UPS

Overview of the Vertiv Liebert APM2 Modular UPS

Vertiv Liebert APM2 is a three-phase online modular UPS for mission-critical facilities, covering 30 to 600 kW in the 400 V version described in the Vertiv product brochure. It is the next-generation mid-size UPS in the Liebert line, evolved from the Liebert EXM2 and APM Plus, and it is intended for small, medium and large data centres as well as commercial, light industrial, telecom and healthcare loads. Capacity is built from hot-swappable power modules, so a site can start with the load it has today and add modules as demand grows rather than replacing the whole system.

Seven Star LLC supplies the Vertiv Liebert APM2 with engineering support in Muscat. For Oman and the GCC this class of UPS is typically specified for data halls, control buildings, hospitals, airports and industrial plants where a single unit must carry a few hundred kilowatts with redundancy, and where service access and mean time to repair matter as much as efficiency.

Operating Principle of the Vertiv Liebert APM2

The Vertiv Liebert APM2 uses advanced three-level IGBT topology together with Silicon Carbide converters. In double-conversion mode the brochure quotes efficiency of up to 97.5 percent. A Dynamic Online mode raises this to up to 98.8 percent while still delivering Class 1 output performance under network faults, load faults and transformer loads, and an ECO mode reaches up to 99 percent for maximum energy saving. The three modes share the same rectifier, inverter, static bypass and battery path, and the unit switches between them seamlessly according to the quality of the incoming supply.

Intelligent paralleling lets several modules share the load and optimises efficiency at partial load, which lowers heat dissipation and cooling demand. Output power factor is unity, with no power derating from 0.5 lagging to 0.5 leading according to the brochure, so the Vertiv Liebert APM2 can carry modern IT loads and also inductive or capacitive industrial loads without reducing its kilowatt rating.

Modular Design of the Vertiv Liebert APM2

Two frame sizes are used. The 30 to 120 kW frame accepts 30 kW power modules in a 2U form factor, can be fitted with internal VRLA or lithium-ion battery modules, and is also available in a compact version without batteries. The 60 to 300 kW and 60 to 600 kW frames use 60 kW 3U power modules and support top or bottom cable entry and optional full switch assemblies. All service parts, including power modules, bypass modules, control module, display and communication modules, are reached from the front, which removes side and rear clearance requirements and allows installation in a row or against a wall.

Because components are hot-swappable, Vertiv quotes a mean time to repair of below 0.5 hours. A 9-inch full-colour touchscreen is the local interface, and monitoring and building management integration is available through SNMP, Modbus TCP and RTU, and BACnet MSTP and IP, with Vertiv Environet Alert and LIFE Services for remote diagnostics.

Key Features of the Vertiv Liebert APM2

• Modular, scalable capacity from 30 kW to 600 kW per unit and parallel operation of up to 6 units for a system capacity of up to 3.6 MW.
• Double conversion efficiency up to 97.5 percent, Dynamic Online mode up to 98.8 percent and ECO mode up to 99 percent.
• Unity output power factor and input power factor of 0.99 at full load with input current distortion of 3 percent or lower.
• Battery flexibility: internal VRLA or lithium-ion modules on the 30 to 120 kW frame, external VRLA cabinets, and compatibility with Vertiv EnergyCore lithium-ion cabinets.
• High-capacity continuous rated charger of 140 A, 600 A or 1200 A depending on frame size.
• Operation up to 50 degrees Celsius ambient with automatic derating above 40 degrees Celsius.
• Conformal coating on all printed circuit boards and IP31 rating with EN 50171 and EN 50121 certifications noted in the brochure.
• Backfeed contacts, phase reversal detection and correction, and short-circuit withstand through bypass with optional fuses on selected models.

Applications for the Vertiv Liebert APM2 in Oman and the GCC

The Vertiv Liebert APM2 suits data centres in Muscat, Sohar and Salalah, government and telecom facilities, and industrial sites that need a reliable power chain for control systems. The brochure also notes that it can back up critical liquid cooling equipment for high performance computing, which is increasingly relevant for new regional data halls. Hot climates matter here: the ability to run at up to 40 degrees Celsius without capacity impact, and up to 50 degrees Celsius with derating, helps in electrical rooms where cooling is limited.

When a project also needs smaller units or battery systems, Seven Star LLC can supply the Vertiv Liebert EXL UPS for larger blocks, the APC Symmetra PX 128kW UPS as an alternative platform, and the EnerSys PowerSafe DU battery for standby energy storage. Our team can compare the Vertiv Liebert APM2 against these options when preparing a technical submittal.

Request a Quote for the Vertiv Liebert APM2

To request the Vertiv Liebert APM2, tell us the required kW rating and redundancy level, the input and output voltage, the battery technology and runtime, and whether top or bottom cable entry is needed. Seven Star LLC will check configuration options, battery cabinets and ancillaries such as maintenance bypass cabinets, and issue a formal quotation for delivery to Oman and the GCC. The Vertiv product brochure is attached to this page, and our engineers can walk through the datasheet details with your design team.
