Six-outlet line-interactive UPS for small offices and retail counters

Uniti Power's Tempo TMP1200IEC is a 1200VA / 600W line-interactive tower UPS for small offices, point-of-sale counters and networking equipment where several devices need protecting from one unit. It combines six IEC 10A outlets, automatic voltage regulation (AVR) and RJ45 data-line surge protection, and its two internal 12V 7Ah batteries give an estimated 40 minutes of backup at a 100W load.

On a shop counter or in a busy office, storms, mains faults and poor-quality grid supply cause dips and spikes as well as outright power cuts. The TMP1200IEC handles routine variation with boost and buck AVR, correcting the voltage without touching the battery, so battery capacity is saved for actual outages. If the supply fails, the load moves to battery in a typical 4-8ms, giving staff time to save work and shut systems down in order.

Built for multi-device workspaces

Six outlets let one TMP1200IEC cover a complete workstation or till point. Typical setups include:

• Retail and point of sale: POS terminals, receipt printers and barcode scanners.
• Small offices: desktop PCs and monitors, network storage and the router that serves them.
• Connectivity and security: network switches, routers, CCTV cameras and access control panels.

How the TMP1200IEC protects your equipment

• Boost and buck AVR: raises a low incoming voltage or reduces a high one, keeping the load within the normal range.
• Input range: 170-280V AC on a 230V nominal supply, connected through an IEC C14 10A inlet.
• Battery backup: typical 4-8ms transfer, with a 230V stepped sine wave output regulated to +/-10% and ±1Hz in battery mode, at 50Hz or 60Hz.
• Data-line protection: RJ45 in and out ports guard a LAN, modem or phone line against surges travelling over the cabling.
• Efficiency: 95% in line mode, 88% in AVR mode and 60% on battery.
• Built-in safeguards: discharge, overcharge and overload protection, with a rear-panel breaker.
• Cold start and auto restart: start the UPS from battery when there is no mains, and it restarts by itself when the mains is restored.

TMP1200IEC or TMP2200IEC?

Both models share the same 139 x 195 x 364mm tower case, six IEC 10A outlets and RJ45 protection. The difference is capacity and battery size:

For a single PC or a router, the smaller TMP850IEC offers three outlets in a 100mm-wide case.

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.

Setting up the TMP1200IEC

Place the UPS under a desk or counter in a protected area with good airflow, at 0 to 40°C and away from damp, dust and direct sunlight. Plug it into a nearby earthed wall socket, then leave it charging with no load for at least 4 hours before first use; the user manual notes that a full charge for the rated backup time takes at least 8 hours.

Connect each device directly to a UPS outlet, not through a power strip or surge suppressor. Laser printers and other motor-driven devices should not be connected, because their in-rush current can damage the UPS.

Monitoring and shutdown

The LCD shows operating mode, input and output voltage, load and battery level. Audible alarms sound every 10 seconds on battery, every second on low battery, every 0.5 seconds on overload and continuously on a fault. The HID USB interface works with the power management built into Windows, macOS and Linux for automated shutdown during an extended outage. There is no expansion slot for a network card.

Standards, warranty and support

The Tempo range is listed in its user manual as meeting IEC/EN 62040-1, -2 and -3, and is a Category C2 UPS, which may cause radio interference in a residential environment. Registered Tempo products in the UK carry a 6-year parts warranty and a 1-year battery warranty: see warranty information for full terms and register your UPS after installation.

Tempo TMP1200IEC questions answered

How many devices can the TMP1200IEC power?
The TMP1200IEC has six IEC 10A outlets, with a combined limit of 600W. Its output power factor is 0.5, so size the load on watts rather than the 1200VA rating.

Does the TMP1200IEC protect network cables?
Yes. RJ45 in and out ports provide surge protection for a LAN, modem or phone line passing through the UPS.

How long will the TMP1200IEC keep equipment running?
An estimated 40 minutes at a 100W load, and about 4 hours to recharge to 90% after a complete discharge.

What batteries does the TMP1200IEC use?
Two internal 12V 7Ah batteries (24V DC). Replacements must be the same type and number; contact Uniti Power technical support if in doubt.

Is the TMP1200IEC a line-interactive or online UPS?
Line-interactive with AVR, transferring to battery in a typical 4-8ms. For continuous online double conversion, see Uniti Power's online models such as the Symphony SPY1500RMi2U.
