Product information

Description

The CyberPower OLS4KERT4UA-IEC UPS Double-conversion 4 kVA 3800 W 15 AC outlets is a line-interactive, double-conversion uninterruptible power supply designed for professional IT environments. With a rated output capacity of 4 kVA (3800 W) and 15 AC outlets including mixed C13 and C19 types, this unit delivers continuous clean power and temporary battery backup. The sealed lead acid battery provides typical autonomy of approximately 6 minutes at full load and around 15 minutes at half load. The UPS can be deployed in either rackmount or tower configurations and is built into a durable black metal housing that meets CE and RoHS compliance.

Advantages

The double-conversion topology provides online voltage regulation and isolation from input disturbances, ensuring consistent sine-wave output and zero transfer time to battery support. Multiple AC outlets allow simultaneous connection of servers, network equipment and peripheral devices without additional power distribution units. The sealed lead acid battery design reduces maintenance needs and simplifies replacement procedures compared with flooded battery types. The robust metal enclosure and flexible rack/tower mounting options make the unit adaptable to rack cabinets or office floors.

Suitable for

Server rooms and data closets requiring continuous clean power.
Network equipment such as switches, routers and firewalls.
Storage arrays and backup systems that need short-term battery support during outages.
Mixed IT racks where multiple device outlet types (C13/C19) are needed.

How to use

Install the UPS in a suitable rack space or place it on a stable surface in tower orientation following the manufacturer’s mounting instructions. Connect critical equipment to the provided AC outlets, prioritising servers and network devices for uninterrupted operation. Plug the UPS mains input to a dedicated, properly grounded AC supply. Use the USB 2.0 port to connect to a management station for monitoring and orderly shutdown configuration if required. Ensure the battery is charged before putting the load on the UPS for the first time and perform regular self-test cycles as recommended by the manufacturer.

Usage recommendations

Place the unit in a well-ventilated environment, maintain ambient temperature within the range specified by the manufacturer, and avoid exposure to moisture or conductive dust. Schedule periodic battery checks and replacement according to runtime requirements and operating conditions. When connecting high inrush devices, verify the total combined load does not exceed the 3800 W rating and distribute loads across outlet groups as appropriate.
