PROLINK UPS Philippines: Choosing the Right Model for Your Business
Philippine power conditions make UPS selection more critical than in most markets. MERALCO distribution lines regularly experience voltage sags during peak demand, brief surges when large loads disconnect, and outages that — while shorter on average than a decade ago — still happen without warning. PROLINK has built its lineup specifically around these conditions, and for Philippine businesses, it remains one of the most practical choices from entry-level office use to enterprise data centre protection.
This guide covers the full PROLINK UPS range available through authorised resellers in the Philippines, how the key series differ, and how to match the right model to your specific load.
Line Interactive vs Online Double-Conversion: The Foundational Choice
Before looking at specific PROLINK models, the most important decision is the UPS technology type.
Line Interactive UPS systems regulate voltage using an automatic voltage regulator (AVR) built into the unit. During a normal brownout or voltage sag, the UPS corrects the output without switching to battery. Battery power only kicks in during a full outage. These units are smaller, quieter, and more affordable — suited for individual workstations and light office loads.
Online Double-Conversion UPS systems run your equipment off a clean, internally generated power source at all times. Incoming mains power charges the battery bank continuously; the equipment never directly touches the mains line. This means zero transfer time during an outage, continuous isolation from voltage noise, and a level of power conditioning that line interactive units cannot match. These are the correct choice for servers, network equipment, and any load where a brief power interruption would cause data loss or system downtime.
PROLINK offers both. The right technology depends on what you are protecting.
The PROLINK Line Interactive Range
PROLINK's Super Fast Charging Line Interactive Series covers 650VA to 3kVA and is available in tower form with or without a USB monitoring interface. The SFT variant extends to 2kVA. A Long Run model (600VA–2kVA) supports extended external battery packs for longer runtime during outages.
These are the units to consider for reception desks, individual staff workstations, point-of-sale terminals, and any non-critical load where you need basic outage protection and surge suppression without the cost of a full online system.
The PROLINK Online UPS Range
For servers, network infrastructure, and critical loads, PROLINK's online lineup is organised into three main series.
Professional II and Professional II+ — 1kVA to 10kVA
The Professional II Series is a single-phase, true online double-conversion UPS available from 1kVA to 10kVA. It comes in Tower and Rack/Tower form factors, each with Standard and Long Run variants. The Long Run models are designed for use with external battery cabinets, allowing you to extend runtime well beyond what a standard internal battery provides.
The Professional II+ Series adds an optional isolation transformer on select models. The isolation transformer provides galvanic isolation between the input and output — eliminating common-mode noise and ground loops that can cause issues with sensitive instrumentation or medical-adjacent equipment. If you are running precision measurement equipment or systems with strict earthing requirements, the II+ with isolation is worth the additional cost.
Both series are the standard recommendation for small to mid-size server rooms, network closets, and SME infrastructure between 1kVA and 10kVA.
Master II — 1kVA to 80kVA
The Master II Series is PROLINK's broadest enterprise line, covering single-phase output (1P/1P) from 1kVA to 10kVA and three-phase output (3P/3P) from 10kVA to 80kVA. Rack/Tower and Tower-only form factors are available across the range. Long Run variants support extended battery cabinets at every capacity point.
A Lithium-ion battery variant is available for Rack/Tower models from 1kVA to 6kVA, offering faster recharge times, a significantly longer battery service life (typically 8–10 years versus 3–5 years for VRLA), and reduced weight — a meaningful advantage in high-density rack environments.
The Master II+ Series covers the 3P/1P configuration (three-phase input, single-phase output) from 10kVA to 30kVA, commonly used when a building's electrical supply is three-phase but the protected equipment runs on single-phase circuits.
For organisations running a dedicated server room with rack infrastructure, the Master II 1P/1P covers the typical 3kVA–10kVA range. For facilities with a small data hall or co-location space, the 3P/3P variants from 10kVA upward are the appropriate starting point.
Master III — 6kVA to 10kVA
The Master III Series is designed for high power density in a compact enclosure, using identical modular power modules for simplified maintenance. It covers 6kVA and 10kVA in both Tower and Tower/Rack configurations, with Standard and Long Run options. The modular architecture means a failed power module can be replaced without taking the entire UPS offline — relevant for environments where scheduled maintenance windows are difficult to arrange.
How to Size Your PROLINK UPS
Getting the VA rating right matters. An undersized UPS trips under load; an oversized one is wasted capital.
- List everything the UPS will protect. Include servers, switches, storage arrays, KVM, patch panels with active devices, and any other powered equipment in the circuit.
- Find the wattage for each device. Check the nameplate or datasheet. If listed in amps, multiply by 220V.
- Convert to VA. Divide total watts by the power factor — use 0.8 as a conservative estimate for mixed loads. If your equipment has modern active-PFC power supplies, the factor is closer to 0.95.
- Add 20–25% headroom. Never run a UPS at 100% rated load. The buffer accommodates startup surges and leaves room for future equipment additions.
- Decide on runtime. Standard internal batteries typically provide 5–15 minutes at full load. If you need longer — for generator switchover or graceful shutdown of large storage systems — specify a Long Run model with an external battery cabinet.
For a practical example: a server rack drawing 1,800W of actual load at a 0.9 power factor requires 2,000VA minimum, with a 25% buffer bringing you to 2,500VA. A PROLINK Professional II or Master II 3kVA would be the appropriate unit.
