Switching power supply mounted on TH-35 (DIN) rail, 15W, 24V DC ZTM-15/24 EXT10000280

Compact power solution for automation

The ZTM-15/24 switching power supply is a 15W power device that generates a stable 24V DC constant voltage. Thanks to its modular design and the ability to mount it on a standard TH-35 (DIN) rail, it is suitable for a wide range of installation applications.

Construction and technical parameters

The device has been designed for maximum functionality in minimal space. Compact dimensions of 1.75 × 5.8 × 9 cm and a weight of just 0.085 kg make it one of the smallest power supplies in this class available on the market. Despite its small size, the power supply offers the full functionality of professional equipment.

The built-in potentiometer allows for output voltage adjustment. An LED diode provides clear signaling of the device's operating status—immediately informing of the correct activation of the power module.

The power supply operates in a wide temperature range from -10°C to +55°C, maintaining full functionality even in difficult environmental conditions. The IP20 protection rating ensures safe operation inside electrical switchboards.

Safety and regulatory compliance

The device is equipped with a comprehensive protection system, including short-circuit protection and resistance to interference from the power grid.

A key safety feature is the isolation transformer, which provides galvanic separation between the power supply network and the low-voltage installation—a fundamental element protecting users from electric shock.

The power supply meets CE certificate requirements, confirming its compliance with European electromagnetic safety and electromagnetic compatibility (EMC) standards.

Practical applications and mounting

In the lighting sector, it is effective for powering stair, ceiling, and garden luminaires.

In the field of building automation, it is used for controlling solenoid valves, electric strikes, and various computer peripherals. Access control systems, monitoring, and intercom and video intercom installations constitute another area of effective use for this power supply.

Mounting requires standard SEP qualifications up to 1kV and basic mounting tools. The installation process includes safely disconnecting the power circuit, mounting the device on a DIN rail, and connecting wires with a maximum cross-section of 2.5 mm² according to the manufacturer's diagram.

The manufacturer of the device is ZAMEL—a Polish company operating in the electrical industry for many years.
