Power Guard 3KVA Online Standard Backup UPS

The Power Guard 3KVA Online Standard Backup UPS is a heavy-duty, high-performance power solution engineered specifically for critical, sensitive equipment. Utilizing true double-conversion online technology, it ensures zero transfer time (0 ms) between line power and battery power, providing clean, pure sine wave electricity to protect high-demand infrastructure from outages, spikes, and line noise.

Internal Battery Configuration

Unlike standard offline units, this online enterprise system relies on a robust internal DC bank to maintain consistent, isolated power generation:

• Battery Arrangement: 6 pieces $\times$ 12V / 8.2Ah sealed lead-acid batteries.

• System DC Voltage: 72 VDC internal bus string.

• Backup Duration: Typically provides up to 10 to 15 minutes at standard workplace loads (intended for bridging power to corporate generators or ensuring clean software server shutdowns).

• Recharge Time: Rapid charging infrastructure allows recovery to 90% capacity within 4 to 6 hours.

Physical Build & Protection

• Robust Architecture: Encased in a rugged Metal Body designed to handle the thermal demands of consistent double-conversion operation.

• Dimensions & Weight: Measures roughly 497 $\times$ 497 $\times$ 365 mm and weighs approximately 25 kg.

• Safety Integration: Incorporates specialized Advanced Battery Management (ABM), lightning protection rating up to 1050 Joules, automatic overload thresholds, and short-circuit protection circuits.

• Smart Cooling: Features a dynamic load-sensing cooling fan system that minimizes noise ($<50\text{ dB}$) during light utilization.

Real-time Interface & Alerts

The unit is outfitted with an integrated control system to manage, monitor, and signal power changes:

• Comprehensive LED/LCD Interface: Shows immediate readings for input/output voltage status, connected load percentages, real-time battery charge state, operational mode, and fault logs.

• Smart RS-232 Communication Port: Allows native integration with central server software across Windows, Linux, and macOS platforms to automate remote scheduling or safe system shutdowns.
