2kVA online rack UPS for busier IT and comms cabinets

The Echo ECH2000RMi2U is a 2000VA / 1800W true online double-conversion UPS designed by Uniti Power for multi-device IT racks, telecoms and networking hardware, security systems and other heavier rack loads. It runs from a 48V DC system of four internal 12V 9Ah batteries, gives a typical 3.6 minutes at full load, and packs all of this into a 2U chassis just 428mm deep.

A busy rack of switches, firewalls, recorders and small servers depends on clean power as much as on backup power. The ECH2000RMi2U rectifies the incoming supply to DC and then rebuilds a pure sine-wave output through its inverter, so the equipment is isolated from mains noise, voltage swings and frequency variation all the time, not only during an outage. Because the inverter is already carrying the load, a mains failure causes no break at all in the output.

Where the ECH2000RMi2U is used

Uniti Power positions the ECH2000RMi2U for multi-device IT racks and heavier loads than the 1kVA model, including network and communications racks, security and CCTV, retail and POS systems, edge computing sites and small server, firewall and switch installations.

Power protection in detail

• Continuous conditioning: online double conversion with a 0ms transfer between inverter and battery modes.
• 1800W real power: a 0.9 output power factor gives more usable power for modern IT and networking hardware.
• Stable output: ±1% voltage regulation, 50 / 60Hz ±0.05% frequency and under 2% THDv on linear loads.
• Tolerant input: accepts 90-275VAC ±5VAC and 40-70Hz ±0.5Hz before drawing on the batteries, with an input power factor above 0.99.
• Efficiency: 90% in line mode and 86% in battery mode.
• Bypass and overload: automatic bypass in under 4ms if the inverter is overloaded or faults; 100-105% load continuously and 105-130% for 60 seconds.
• ECO mode: selectable from the front panel, with a transfer of under 10ms between ECO and battery operation.

Batteries and runtime

Four internal 12V 9Ah batteries make up the ECH2000RMi2U's 48V DC battery system. A 1A charger restores them to 90% in around 5 hours after an outage.

For applications that need longer or expandable runtime, Uniti Power's ECH3000RMi2UER is the Echo model built to work with external battery modules.

Runtimes are typical values for new, fully charged batteries at 25°C, provided as a guide only. Actual runtime depends on battery age, temperature and the type of load.

Installation and set-up

The chassis measures 439.8 x 88 x 428mm and weighs 18kg, so two people or suitable lifting aids are advised when fitting it. It mounts in a 19-inch rack with the supplied rack ears, takes power through an IEC C14 inlet, and the user manual shows four IEC C13 outlets on the rear. Leave 200mm clear behind the rear panel for airflow.

From the programmable LCD panel the installer can set the output voltage (208, 220, 230 or 240VAC, 230V default), fix the output frequency at 50Hz or 60Hz or leave it auto-adaptive, enable auto restart when mains returns, and switch ECO mode, bypass output, EPO and ROO on or off.

Monitoring and communications

Standard interfaces are RS232, USB and an EPO / ROO dry-contact port. The external slot is short-depth and takes the optional UPNETG2S network management card, giving Gigabit Ethernet monitoring with SNMP, Modbus TCP, MQTT and REST API support. Pair it with WinPower G2 software for live status, event logs and safe automated shutdown.

Standards, warranty and support

The ECH2000RMi2U is CE marked, IP20 rated and runs at under 50dB. Its user manual lists EMC to IEC 62040-2 Category C2 and safety to EN IEC 62040-1.

Echo products registered in the UK are covered for 3 years on parts and 1 year on batteries. Full terms are on the warranty information page, and you can register your UPS after installation. Technical support and installation and commissioning are available from Uniti Power.
