PowerShield Defender Rackmount 1500VA UPS (PSDR1500)

The PowerShield Defender Rackmount 1500VA is the higher-capacity sibling of the PSDR800 — bringing 900W of power protection and industry-leading 8-10 year long-life batteries into a compact 2RU shallow-depth rack form factor. At just 300mm deep, it fits perfectly into wall-mounted comms cabinets, network enclosures, and edge-of-network installations where space is limited and reliability is critical.

With double the battery capacity of the PSDR800 and long-life batteries that dramatically reduce replacement frequency, the PSDR1500 is the smart choice for installations that demand more runtime and less maintenance.

Key Features

Industry-Leading 8-10 Year Long-Life Batteries
The PSDR1500 ships with 2 x 12V 9AH long-life batteries with a design life of 8-10 years - significantly longer than standard UPS batteries. This dramatically reduces battery replacement costs and maintenance requirements over the life of the unit.

Compact 300mm Shallow Depth
At just 300mm deep, this is purpose-built for shallow wall-mounted comms cabinets and compact rack enclosures. Fits standard 19-inch 2RU racks and can also be used as a standalone tower unit.

Automatic Voltage Regulation (AVR)
Buck and Boost AVR automatically corrects unstable fluctuating utility voltages, bringing them within 10% of nominal range to protect connected 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 on mains power, reducing audible noise and improving efficiency for the vast majority of its operating life. Less than 5dBA at 1 metre - ideal for quiet office and AV environments.

User-Replaceable Hot-Swap Battery
Batteries are easily user-replaceable and hot-swappable, extending the service life of the UPS and reducing e-waste without needing a technician.

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

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

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

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

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.
