Line-interactive UPS with buck-and-boost AVR offers network-grade power protection in extreme temperatures from -40°C to 80°C.

  • Recommended for remote locations where temperatures range within -40°C and 80°C
  • Protects equipment against blackouts, brownouts, overvoltages, surges and line noise
  • Keeps power running during prolonged outages to allow time for safe system shutdown
  • Maintains continuous 120V nominal output during brownouts and overvoltages
  • Optional WEBCARDLXMINI network interface supports Auto Probe feature


1.5kVA/1.2kW/120V Battery Backup for Applications in Low- and High-Temperature Extremes
This SmartPro® line-interactive SMART1524ET UPS system with hardwire AC input/output offers a wide operating temperature range and provides constant and reliable backup power to critical equipment in harsh environments, including outdoor and industrial equipment. It prevents surges, spikes, overvoltage, undervoltage and blackouts from damaging equipment, destroying data and contributing to costly downtime.

Ideal for Running Networking, Security or Traffic Equipment in -40°C to 80°C Temperatures
The SMART1524ET is ideal protection for a wide variety of industry-specific IT, communications, edge computing, security, surveillance, traffic signage and traffic camera equipment in remote locations where temperatures are typically within -40°C and 55°C (for max output), -40°C and 75°C (for up to 1200W output) or -40°C and 80°C (for up to 1000W output). Internal circuitry is covered with a conformal coating that protects against extreme temperatures. Applications range from oil fields, offshore oil rigs and other industrial locations to remote security and military applications to traffic-related setups involving signals and cameras.

Reliable, Expandable Battery Backup Keeps You Operational Through Power Outages
Backup support allows you to safely maintain the operation of critical traffic/industrial equipment and other applications requiring reliable extended UPS runtime in demanding environments. A battery connector kit with wireable contact pins lets you connect your own 24V battery banks up to 200Ah (batteries and cables not included). A temperature sensor monitors the battery terminals and customizes charging to optimum levels to extend the lifespan of the connected batteries.

Optional WEBCARDLXMINI Network Interface Offers 24/7 Remote Access for Monitoring and Control
The Java-free HTML5-based WEBCARDLXMINI (sold separately) enables full remote access for site power and UPS status monitoring, configuration, control and email notifications via secure web browser, SNMP, telnet or SSH. It supports 10/100 Mbps auto-sensing for optimum communication with an Ethernet network. Automated alerts help prevent accidental overloads, power loss and downtime. WEBCARDLXMINI allows you to use the Auto Probe feature, which can prevent costly service calls by automatically rebooting non-responsive network devices. Note: WEBCARDLXMINI has a temperature range of 0°C to 70°C, as measured inside the UPS housing.

Built-in Input/Output Dry Contacts and 24V DC Temperature-Controlled Fan Power Outlet
Six sets of output dry contacts support Normally Open (NO) or Normally Closed (NC) signaling of user-configurable UPS conditions, such as On Battery, Low Battery or UPS Fault to other integrated devices. One set of input dry contacts supports the connection of one user-supplied contact-closure sensor for remote notification via WEBCARDLXMINI and local notification via front-panel LCD. A temperature-controlled 24V DC output power jack supports optional user-supplied fan installation to control over-temperature conditions in equipment enclosures.

Automatic Voltage Regulation (AVR) Corrects Low- and High-Voltage Conditions
AVR protects your equipment from incremental hardware damage, data loss and performance problems caused by brownouts and overvoltages. The SMART1524ET can correct brownouts as low as 88V and overvoltages as high as 152V with user-configurable buck-and-boost settings, all while keeping the battery fully charged and ready to take over in case of power failure.

Premium Protection from EMI/RFI Line Noise Helps Your Equipment Perform Better
This UPS system filters out disruptive electromagnetic and radio frequency interference that can inflict hardware damage or data loss. This EMI/RFI filtering also helps your connected components perform better and last longer.

Designed for High Efficiency to Help You Save Money and Protect the Environment
A >95% efficiency rating reduces BTU emissions, energy consumption and, ultimately, your energy costs.

Intuitive Front-Panel Interface for Convenient Monitoring
Front-panel LEDs report operating mode (green), alarm (yellow) and fault (red). The LCD screen with select and scroll buttons offers a wide variety of UPS status and site power information, control options, UPS configuration settings and event logs.

Advanced Communications Ports Allow for Automatic Saves and Shutdowns
RS-232 and HID-compliant USB ports connect to a computer running free downloadable PowerAlert® software to enable a safe, automatic system shutdown in case of a prolonged power failure.

Versatile Installation Options
Hardware is included for mounting the SMART1524ET in 3U of space in an EIA-standard 19-inch 2-post or 4-post rack or on a flat desktop surface. The reduced-depth housing requires less than 10 inches of equipment rack depth for convenient two-point installation.
