APC SY128K160H Symmetra PX 128kW Scalable to 160kW UPS

Overview

The APC SY128K160H is a Symmetra PX modular, scalable three-phase online UPS delivered as a 128kW frame that can be expanded to 160kW / 160kVA of protected capacity, engineered for data centers and large industrial facilities that need concurrently maintainable, N+1 redundant power protection at 400/415V. Seven Star LLC supplies it across Oman and the GCC with genuine stock, technical pre-sales guidance and after-sales support for large power infrastructure projects in Muscat, Sohar, Salalah and neighboring markets. Facility engineers and data center operators specify this UPS when a critical three-phase load needs scalable, modular online protection that can grow in capacity over time without a full UPS replacement as the facility expands.

The Symmetra PX platform that the APC SY128K160H belongs to was engineered by Schneider Electric around hot-swappable power modules, allowing capacity and redundancy to be added or serviced without powering down the protected load. This modular architecture is a major reason the APC SY128K160H is specified for mission-critical facilities across the GCC where downtime for maintenance is simply not an acceptable option.

Measurement and Working Principle

The APC SY128K160H uses double-conversion online topology at the three-phase level, continuously rectifying incoming AC to DC and reinverting it to a regulated AC output so the protected load never experiences a transfer event during a utility disturbance. Because the APC SY128K160H is built from independent, hot-swappable power modules working in parallel, the loss or removal of any single module for maintenance does not interrupt protection to the connected load, provided the frame is configured with adequate redundancy. The unit’s integrated Network Management Card and system display continuously report module health, battery status, and load distribution, giving facility operators real-time visibility into a UPS system that may be protecting an entire data hall.

Engineering Design of the APC SY128K160H

Housed in a large-format frame measuring 1800mm W x 1070mm D x 1991mm H and weighing approximately 2518kg fully configured, the APC SY128K160H delivers a hard-wired 380/400/415V three-phase output through a 5-wire connection (three phases, neutral, and ground) sized for serious industrial and data center power distribution. The APC SY128K160H uses VRLA battery modules with a recharge time of approximately 3.5 hours and supports Emergency Power Off (EPO) circuitry for facility-wide safety compliance. Communications run through dual SmartSlot bays paired with a Network Management Card, and the unit is rated for operation across a 0-40°C temperature range and 0-95% relative humidity, with a noise level of approximately 63dB under normal operation. Its modular design allows additional power modules to be added within the same frame as load requirements grow, scaling protected capacity up to the full 160kW rating without replacing the installed base frame.

Key Features

• The APC SY128K160H scales from 128kW to 160kW within the same frame using hot-swappable power modules.
• The APC SY128K160H supports concurrent maintenance, allowing module service without interrupting protected load power.
• The APC SY128K160H delivers hard-wired 400/415V three-phase output suited to serious industrial power distribution.
• The APC SY128K160H includes Emergency Power Off circuitry and dual SmartSlot communication bays.
• This Symmetra PX frame operates reliably across a wide 0-40°C temperature and 0-95% humidity range.

Industrial Applications

The SY128K160H is commonly specified to protect data hall power distribution, colocation infrastructure and large industrial control systems in Oman’s growing data center and process industries. In heavy industrial settings it backs up central control rooms, large SCADA and DCS server farms and critical process automation infrastructure where a facility-wide outage would have serious operational or safety consequences. Because the system supports concurrent maintenance, it suits 24/7 operations in the GCC oil and gas, petrochemical and utility sectors, where scheduled downtime for UPS servicing is difficult to arrange around continuous production.

System integrators and consulting engineers across Muscat and the wider GCC also specify the APC SY128K160H for new-build data centers where the capital project needs to start with a lower initial power module count and grow toward the full 160kW rating in phases as tenant or facility load increases over several years.

Because the APC SY128K160H is a hard-wired, professionally installed three-phase system, Seven Star LLC works alongside consulting engineers and electrical contractors from the specification stage through commissioning, ensuring the frame configuration, battery runtime, and redundancy level are correctly matched to the facility’s actual critical load before installation begins.
