PowerShield Defender Rackmount 800VA UPS (PSDR800)

The PowerShield Defender Rackmount 800VA is built for one specific job — fitting a full-featured UPS into a shallow comms cabinet. At just 230mm deep, it is the shallowest rack-mountable UPS on the Australian market, making it the go-to choice for wall-mounted comms racks, network cabinets, CCTV enclosures, and NAS installations where standard-depth rack UPS units simply will not fit.

Engineered with all the trusted features of the Defender range — AVR, LCD display, hot-swappable battery, SNMP slot, and NetGuard software — packed into a compact 2RU rack form factor that can also stand upright as a tower unit.

Key Features

Compact Shallow Depth Design
At 230mm deep, this is the perfect UPS for shallow, wall-mounted comms cabinets and tight rack enclosures. It can also be used standing upright when rack space is not available.

Automatic Voltage Regulation (AVR)
Buck and Boost AVR automatically corrects unstable fluctuating utility voltages, bringing them within 10% of nominal range to protect valuable equipment without drawing on the battery.

Informative LCD Display
Modern LCD display shows input voltage, output voltage, load level, battery capacity, and remaining backup time at a glance. Status indicators for AC mode, battery mode, low battery, fault, and overload.

Fan-Free Silent Operation
Engineered to run without fans when operating on mains power - reducing audible noise and improving efficiency. Less than 40dBA operation makes it ideal for quiet office and AV environments.

User-Replaceable Hot-Swap Battery
The battery is user-replaceable without tools, extending the life of the UPS and reducing e-waste. No technician required for routine battery replacement.

Intelligent SNMP Slot
Optional SNMP card (PSSNMP, sold separately) enables real-time remote monitoring, event notifications, scheduled shutdowns, startups, and reboots - without being on site.

HID Plug and Play
Built-in HID USB connection provides simple UPS management with Windows, Apple, Linux, NAS devices, and industrial controllers without any additional software.

PowerShield NetGuard Software
Free downloadable NetGuard software provides complete power monitoring including input/output voltage, battery remaining time, and load level. Ensures safe, orderly shutdown during prolonged outages. Supports Windows, Linux, Unix, and Mac.

Cold Start Function
The UPS can start on battery only and support its connected load - ideal for short-term power needs or locations without mains.

Off-Mode Charging
Continues charging internal batteries even when the unit is switched off, ensuring dependable backup power whenever needed.

Auto Restart on AC Recovery
Automatically powers back up and restores connected equipment as soon as mains power returns after an extended outage.
