Power Devices

Altech Power Supplies include compact DIN rail units, slimline models, wide-input supplies, DC UPS systems, and accessories like buffer modules and UPS battery modules.

A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. Altech Power Devices deliver reliable power and backup solutions for industrial applications. The range includes slimline and compact DIN-rail power supplies with universal AC input, high efficiency, and full protection features; low-profile models for tight spaces; and all-in-one DC-UPS systems that combine power supply, charger, and backup in one unit. For fast, maintenance-free protection against brief outages, Altech also offers ultra-capacitor backup modules with long service life. Together, these devices ensure safe, efficient, and uninterrupted operation across control and automation systems.
