Mitsubishi UPS FW-V20-5.0K
The UPS FW-V20-5.0K is a tower-style, line-interactive uninterruptible power supply designed for small servers, network equipment, and industrial control systems. The UPS FW-V20-5.0K delivers a clean sine-wave output of 5.0 kVA / 3.5 kW, ensuring seamless switchover upon mains failure with zero transfer time (“no-break”). With an AC input range of 200–240 VAC (±10 %) at 47.5–63 Hz and a power factor ≥ 0.95, the UPS FW-V20-5.0K excels in maintaining power quality even under fluctuating line conditions.
Key Features
-
Topology: Line-interactive inverter ensures the UPS FW-V20-5.0K switches to battery without interruption.
-
Battery Runtime: Built-in valve-regulated lead-acid battery provides 10 minutes of full-load backup (initial spec, 25 °C) with a 5-year expected service life at 20 °C.
-
Output Performance: Single-phase 3-wire output selectable between 200–240 VAC or 100–120 VAC, sine-wave, ≥ 300 % peak-current tolerance, and ≤ 3 % THD on a linear load.
-
Interfaces: RS-232C (D-sub 9-pin), USB Type-B, open-collector alarm outputs (UPS fault, on-battery, low battery), and opto-isolated shutdown input.
-
Reliability & Service: Forced-air cooling (fan life 5 years at 20 °C), operating range 0–40 °C (recommend 20–30 °C), ≤ 95 % RH non-condensing; dimensions 250 × 700 × 1,010 mm (W×H×D); weight ~186 kg.
End-of-Life and Replacement
The UPS FW-V20-5.0K was discontinued as of June 2024. Mitsubishi now recommends the FREQUPS FW-S series paired with dedicated transformer units as replacements. They offer equivalent backup performance:
| Discontinued Model |
Replacement Combination |
| UPS FW-V20-5.0K (5.0 kVA) |
• FW-S10-5.0K + FW-STR-5.0K• FW-S10T-5.0K + FW-STR-5.0K |
