The Mitsubishi UPS FW-V10-1.0K is a tower-style, line-interactive uninterruptible power supply designed to protect branch offices, network closets, and control panels; the FW-V10-1.0K delivers 1.0 kVA / 700 W of pure sine-wave output with zero-transfer “no-break” switching, and the FW-V10-1.0K ensures seamless continuity during brownouts, spikes, or momentary outages.
Mitsubishi UPS FW-V10-1.0K
The Mitsubishi UPS FW-V10-1.0K is a tower-style, line-interactive uninterruptible power supply designed for branch offices, network closets, and control panels. Delivering 1.0 kVA / 700 W of pure sine-wave output, it bridges brownouts, surges, and momentary outages with zero-transfer “no-break” switching to safeguard critical equipment.

Key Features
Line-Interactive Inverter Topology
Instantaneous switchover to battery without interruption.
Wide Input Range & High Power Factor
Operates on 85–144 VAC (±0 %) at 47.5–63 Hz with PF ≥ 0.95.
Reliable VRLA Battery
Valve-regulated lead-acid battery with a 5-year expected life (@ 20 °C); provides 10 minutes of full-load runtime (25 °C) and recharges to 90 % in 8 hours.
Flexible Output Configuration
Six NEMA 5-15R outlets (2P15A earthed) in three independent circuits plus one M4 terminal block; selectable 100–120 VAC ± 2 % sine-wave, 300 % peak-current tolerance, ≤ 3 % THD.
Comprehensive Communications & Control
RS-232C (D-sub 9-pin) and USB Type-B ports, open-collector alarm outputs (UPS fault, on-battery, low battery), and optoisolated shutdown input.
Compact & Quiet
170 × 270 × 453 mm (W×H×D); ~21 kg; 45 dB at 1 m (A-weighted); forced-air cooling (fan life 5 years @ 20 °C).
Safety & Compliance
UL 1778 certified; VCCI Class A and FCC Class A EMC compliance; CE marking available on request.
