The TIS series switching power supplies are specially developed for use in industrial process control systems and machine tools. With high-quality specifications and strong resistance to electrical interference, they deliver dependable power to sensitive equipment even in tough industrial conditions.

By adding optional function modules, system-specific requirements can be easily met using a standard unit. For example, the UDS module can upgrade the power supply into a full DC-UPS with automatic battery backup—an essential feature in setups that need a delayed system shutdown. A signal module can also be added for monitoring and control.

When parallel operation with active power sharing is required, a redundancy option is available. Thanks to this adaptability, TIS series power supplies provide a reliable and cost-efficient choice for a wide range of industrial applications.

Power Supplies with Redundancy Function

The redundancy option enables parallel operation of up to five units. Built-in decoupling diodes and current share lines allow true N+1 redundant systems with active current sharing across all connected units. An integrated alarm relay is included to provide a failure signal if a single unit goes down.

This option is available for the TIS 150 W, 300 W, and 600 W models.

Note: The redundancy option cannot be combined with other function modules.

Power Supplies with Powerfail Functions

These models integrate three essential features often required in process control applications:

• AC Powerfail signal (relay contact)
• Power Good signal (relay contact)
• Remote On/Off control

This makes them especially suited for industrial systems where reliable monitoring and control are critical.

DC-UPS System (UDS Option)

In addition to standard power supply operation, these models feature a professional battery management system designed to charge and monitor an external battery.

• Seamless backup power: In case of mains failure, the system automatically switches to battery power with no interruption to the DC output. Once mains power is restored, the battery is disconnected and recharged.
• Flexible backup time: Limited only by the capacity of the connected battery and the load demand.
• Adjustable charging: Charge current and voltage can be configured to match the requirements of the battery type.
• Alarm functions: Power fail alarm via relay contact Low battery alarm via independent relay contact High cell resistance alarm triggered during periodic battery status checks
• Protection features: Battery is fully monitored and protected under all operating conditions Power supply remains short-circuit protected, even in backup mode For safety, the external battery should be equipped with a fast-blow fuse
• Battery mode activation: Enabled by interconnecting pins 7 and 8
