Product Details:

S-35W series UPS backup power supply

Stabilized professional switching power supply (SMPS).

Ideal for continuous use combined with LED strips, video surveillance, amateur radio, and all the 24V equipment that requires constant voltage, power, and reliability.

The perforated metal case permeates excellent heat dissipation and durability.
Protected from small overloads and power surges.

The connection to the mains and to the LED strips is via a terminal block integrated into the power supply.

The 24-volt direct current (DC) output at 1.5A constant makes it perfect for use with LED Strips.

The power supply guarantees a transformation efficiency of 88%.
