Lightwave LW UPS1500 (1500VA / 900W)

Lightwave LW UPS1500 (1500VA / 900W)

• Desktop PCs + monitors
• Networking equipment (routers, switches, modems)
• Small servers or workstations
• CCTV/DVR systems
• Other sensitive electronics (not ideal for heavy inductive loads like large motors or medical equipment due to modified sine wave output)

  Lightwave LW UPS1500 (1500VA / 900W) is a line-interactive Offline/Standby UPS with Automatic Voltage Regulation (AVR), popular in markets like Kenya and the UAE for home/office use.

  Key Specifications

  • Capacity: 1500VA / 900W (real power output).
  • Type: Line Interactive with AVR (boost/buck voltage regulation).
  • Input Voltage: Typically 145V–280V AC (or 140V–300V in some listings); 50/60 Hz ±10%.
  • Output Voltage: 230V ±10% (modified sine wave in battery/inverter mode).
  • Transfer Time: <10 ms (typically 4–8 ms).
  • Battery: 2 × 12V sealed lead-acid, maintenance-free.
  • Recharge Time: ~6–8 hours to 90%.
  • Backup Time: ~5–15 minutes at full load; ~10–45 minutes depending on load (e.g., PC + monitor). Varies significantly with connected devices.
  • Outlets: 3 × standard 3-pin sockets (some models mention universal).
  • Protections: Surge/spike suppression, overload/short circuit (fuse + current limiting), high/low voltage protection, overcharge protection.
  • Features: LED indicators (or LED display in some variants), auto-restart, DC start, intelligent battery management, audible alarms.
  • Dimensions: Approx. 325 × 145 × 220 mm; Weight ~10 kg (shipping ~11 kg).
  • Noise: <45 dB.
  • Operating Environment: 0–45°C, 20–90% humidity (non-condensing).

  Datasheet: Available on the manufacturer’s site.

Pros:

• Good capacity for the price.
• AVR helps handle voltage fluctuations without draining the battery.
• Compact tower design.
• Basic surge protection and battery management.

Cons:

• Modified sine wave (may not suit all sensitive electronics).
• Backup time is load-dependent and relatively short at higher loads.
• Basic interface (LEDs, no advanced LCD/network management like premium brands).
