GP600 600VA 360W Offline UPS

Reliable 600VA Offline UPS for PC and Office Equipment

The GP600 is ulinkeep’s compact standby (offline) tower UPS for desktop PCs, cash registers, routers and small network devices. When utility power fails, it transfers to battery in 4–8 ms and keeps equipment running long enough to save files and shut down safely — no lost orders, no corrupted data.

The classic vertical tower wears a dark-grey front bezel and weighs about 4.4 kg, so it slips under a desk or beside a weak-current cabinet. The rear panel is practical: two universal output sockets (socket standard can be customized per country), an optional USB communication port, a set of RJ45/RJ11 network surge-protection ports, and the AC input cord. Side vents keep it running quiet, and the front offers an optional LED or LCD that shows green for normal, orange for battery mode and red for fault. Setup is as simple as a power strip — plug and play.

Rear Panel: Universal Sockets, USB & Network Surge Protection

Two universal output receptacles accept local plugs for a PC host, monitor and POS terminal; the optional USB communication port reports UPS status to a connected PC. A pair of RJ45/RJ11 ports pass the network or phone line through the UPS and absorb lightning surges, protecting the router, switch and network card on the other side. The AC input keeps charging the battery even when the UPS is switched off (off-mode charging), and supports cold start so the unit can power up directly from battery.

AVR Voltage Stabilization for Unstable Grids

Input accepts 110/120/220/230V with boost/buck AVR. When mains runs high or low, the offline UPS stabilizes voltage first — the 140–300 VAC input is automatically adjusted to 220V ± 10% — and only switches to battery on a real outage, saving battery life. It is the right choice for regions with unstable grids.

The RJ45/RJ11 pass-through adds lightning and surge protection for connected routers, switches and phones — practical insurance for small network and weak-current rooms.

Efficient Heat Dissipation, Low Noise

The plastic shell carries dense side ventilation holes that pull heat away during backup, while the passive design keeps operation quiet enough for offices, counters and studios.

Instant Transfer Keeps Work Uninterrupted

On utility failure the GP600 transfers to battery in 4–8 ms typical (13 ms max) — short enough that a normal PC never reboots, giving you time to save work and shut down gracefully. Auto-restart on AC recovery and cold start are both supported.

Application Scenarios for Office and Retail

This offline UPS fits places where short backup and stable voltage matter more than long runtime: SMB offices (front-desk PC, printer, monitor), chain-store POS counters (POS + scanner + receipt printer), small network and weak-current rooms (router, switch plus RJ45 surge port), education and training labs, and clinics or studios.

In regions with unstable grids, the boost/buck AVR regulates high or low mains first so the battery is saved for real outages. If you need DC backup for routers and IP cameras instead, our B600T mini DC UPS covers 12V DC loads.

Optional Sockets & OEM/ODM Customization

Ulinkeep supports full OEM/ODM for this standby series (400VA–2000VA): logo silkscreen and panel customization, drawing-based and sample-based development, custom socket standards (EU/US/UK/universal), voltage output and packaging.

Packaging and logo/graphic customization start from 1,000 sets — custom design in 3 days, samples in 7 days, free replacement parts and online technical support during cooperation, a proven path for distributors, computer channel resellers and system integrators building their own brand.

GP600 Offline UPS Specifications

Backup comes from a 12V lead-acid battery, giving roughly 10–15 minutes for a standard desktop PC. The specification sheet below is shared by the 400VA–2000VA standby series; the GP600 is the 600VA / 360W model.
