Product information

Description

The CYBERPOWER CPS3500PRO is an online double-conversion uninterruptible power supply (UPS) that delivers 3.5 kVA (2450 W) of continuous, regulated power. Equipped with sealed lead‑acid (VRLA) batteries (12 V, 200 Ah), three AC outlets and an LCD tower enclosure, it is designed to provide stable power to servers, network equipment, computers and other critical loads during mains interruptions or fluctuations. The unit includes a large LCD showing load level, battery status and voltage information, and supports AVR adjustment for a pure sinewave output.

Advantages

The double-conversion (online) topology provides continuous isolation between input and output, ensuring clean, regulated power without transfer time during outages. Pure sinewave output and adjustable AVR increase compatibility with sensitive equipment. The built-in VRLA batteries offer reliable backup capacity, while the LCD panel gives clear, at-a-glance status information. The tower form factor and compact footprint make the UPS suitable for server rooms and small data closets.

Suitable for

  • Servers and rack or tower network devices
  • Workstations and desktop computers
  • Networking equipment such as routers and switches
  • Critical devices requiring continuous regulated power

Key specifications

  • Output power: 2450 W
  • Power capacity: 3.5 kVA (double-conversion / online)
  • Batteries: VRLA, 12 V, 200 Ah
  • AC outlets: 3
  • Form factor: Tower with LCD
  • Colour: Yellow
  • Dimensions (approx.): 330 × 260 × 440 mm
  • Weight: 37 kg

How to use

Install the UPS on a stable, level surface with adequate ventilation and connect the UPS input to a grounded AC mains outlet. Connect critical equipment to the three AC outlets on the UPS. Configure AVR and monitoring settings via the front LCD or the management interface as required. Ensure batteries are charged before use and perform initial runtime tests to verify connected loads receive power during mains failure.

Usage recommendations

Place the UPS in a temperature-controlled, dust-free environment, perform periodic battery checks and replace VRLA batteries according to the manufacturer’s service guidelines. For critical installations, test load transfer and runtime under expected load conditions and consider professional installation for server-room deployments.
