APC SRT 1500VA Overview
General Features
Power Density
More real power in watts, 0.9 pf on the SRT1500RMXLA
Green / ECO Mode
The SRT1500RMXLA can achieve 95% efficiency, which helps save utility and cooling costs while still maintaining performance and reliability. This operating mode bypasses unused electrical components in good power conditions to achieve higher operating efficiency without sacrificing protection and maintaining Energy Star compliance
No Battery Needed
The SRT1500RMXLA can immediately protect equipment when power returns after a complete discharge of the battery
Built-In Energy Meter
Measures energy use and displays UPS efficiency in various modes of operation for energy tracking
Optional Additional Battery Packs
These can be added to increase the overall runtime for business-critical devices such as mid-range Windows/Linux servers, business-critical servers, Wi-Fi applications, data network backbones, data storage, medical labs, imaging systems, ATM machines, programmable logical controllers (PLCs), cellular sites, and Voice-over IP devices (VoIP)
Switched Outlet Groups
Provides the ability to control a group of receptacles independent from the main UPS. This feature allows several options such as the ability for you to reboot hung devices without cycling the entire UPS, the shedding of non-critical loads based on a wide variety of parameters, scheduling time off to conserve energy, and sequenced turn on/off
Enhanced Intelligent Battery Management
Temperature compensated charging extends life and advanced algorithms recommend a replacement date. The UPS can inform users which batteries need to be replaced in advance and automatically detect when additional battery packs are added
Graphical LCD
An intuitive backlight LCD provides information on load indicator, battery charge, output/input voltage, runtime, load, and battery health. It is also available in multiple languages. The backlight's different colors allow users to identify the UPS' normal vs. attention status

APC SRT 1500VA Reviews
Network claims are deceptive
By Paul
Rated 2 out of 5
Date: 2026-07-15
Advertises network manageable via Ethernet. This is false advertising. It has no native network capability and you must purchase a separate $300 APC network management card to activate that capability. The built in RJ45 port is for an included RJ45 to serial adapter cable only. APC must be connected to a compatible computer to be managed and can only execute a graceful shutdown on that one product. Does not have the ability to be directly plugged into your switch/network and be managed via IP address. Buyer beware - APC is not being transparent in its marketing.
