Schneider Electric BV650I-MSX APC Easy UPS 650VA, 230 V

BV650I-MSX APC Easy UPS 650 VA, 230 V with AVR

The BV650I-MSX is an APC Easy UPS rated 650 VA (375 W), a compact line-interactive UPS for 230 V single-phase equipment. It has four universal output sockets, a BS 1363 British-style input plug on a 1.5 m cable, automatic voltage regulation and a sealed lead-acid battery inside. Seven Star LLC supplies the BV650I-MSX in Oman and the GCC as an independent supplier based in Muscat.

It is a small-desk and small-office unit, intended for computers, routers, point-of-sale equipment and similar loads, and it can also be mounted on a wall. At 4.5 kg it is the lighter of the two Easy UPS models on this lane, the other being the BV800I-MSX at 800 VA / 450 W.

BV650I-MSX technical specifications

How the BV650I-MSX protects a load

The datasheet gives the topology as line interactive with a stepped approximation to a sine wave on battery. In normal operation the mains passes through automatic voltage regulation, which corrects moderate over- and under-voltage without using the battery; if the supply fails or leaves the window, the UPS transfers to battery in 6 ms typical : 10 ms maximum.

Stepped-sine output is accepted by most IT equipment and switch-mode power supplies, but some loads with active power-factor correction or sensitive motors prefer a pure sine output, which this class of UPS does not provide. Surge energy rating is 156 J.

Sizing a load for the BV650I-MSX

Add up the watts of the equipment, not just the VA: this UPS is limited to 650 VA and 375 W, whichever is reached first. As a general rule leave 20 to 25 percent margin so that the UPS is not at its limit and the battery runtime is not minimal. The datasheet does not state runtime, and runtime depends strongly on load, battery age and temperature, so ask us if runtime for a specific load must be confirmed.

There is no extendable runtime on this model: the extendable-runtime and battery-module fields on the sheet are 0, so the internal battery is the only energy source.

As an illustration, a broadband modem, a router and a small desktop PC with monitor typically stay comfortably inside the 375 W budget of this smaller model, but add a printer or a second PC and the margin disappears quickly.

Indications and alarms on the BV650I-MSX

The datasheet describes an LED status display showing on-line and on-battery states, and alarms for on-battery operation, a distinctive low-battery alarm and a continuous tone for overload. There is no USB communication port (USB compatible: No), so the UPS cannot report status to a computer; protection is local and audible only.

Because there is no data link, shutdown of unattended computers has to be handled by sizing the battery for the time the equipment needs, or by choosing a UPS model with communication.

BV650I-MSX against the other Easy UPS model

Both share the same topology, four sockets, British-style input plug and 24 month warranty. Choose by the connected load and the headroom you want.

Selection checklist for the BV650I-MSX

• Connected load below 375 W and 650 VA, with margin.
• Input plug is BS 1363 British type, common in Oman and the GCC.
• Four universal outlets are enough for the equipment.
• No communication port is acceptable.
• Stepped-sine output is acceptable to the load.
• Room stays within 0–40 °C.

Installation and care of the BV650I-MSX

Place the UPS where air can reach its sides, away from direct sun and heat sources, or hang it on the wall using the wall-mount compact format. The operating range on the datasheet is 0–40 °C, and the humidity limit is 0–90 %. Charge the battery for several hours before relying on it and test it with a short supply interruption at commissioning.

The internal sealed lead-acid battery has a stated life of 3–5 year(s), and heat shortens it. In rooms that run warm, plan on the lower end and note the replacement date on the unit.

Where the BV650I-MSX is used in Oman and the GCC

Short outages and voltage dips are common enough in offices, shops and homes to justify protecting routers, PCs, cash registers and CCTV recorders. The UPS gives enough time to save work and shut down, and keeps network gear alive across short interruptions. Because an air-conditioned room is not guaranteed in small premises, keep the unit out of hot storerooms and car-park cabins.
