Switching power supply mounted on TH-35 (DIN) rail, 60W, 12V DC ZTM-60/12 EXT10000283

Professional switching power supply for automation and low-voltage installations

The ZTM-60/12 switching power supply is an advanced power device from the EXTA series, designed for mounting on a standard TH-35 (DIN) rail. This model serves as a foundation for the stable power supply of building and industrial automation systems, offering an output power of 60W at a constant voltage of 12V DC.

Modular design and advanced electronics

The device features a compact modular design with dimensions of 90 × 52.5 × 58 mm, which corresponds to three standard DIN rail modules. The 52.5 mm width allows for optimal space management within the electrical distribution board.

At the heart of the power supply is a transistor switching converter, which ensures high energy efficiency and significantly smaller dimensions compared to traditional transformer power supplies of the same power. A key safety element is the isolation transformer, which guarantees galvanic separation between the power grid and the low-voltage installation.

The design includes an adjustment potentiometer, allowing for precise correction of the output voltage within the range of 11-13V DC. An LED diode signals the device's operating status and the presence of output voltage, facilitating installation diagnostics.

Operating parameters and electrical protections

The power supply generates a stable 12V DC constant voltage with a maximum output current of 5A, providing a load capacity of 60W. The device operates in temperatures from -10°C to +55°C and has an IP20 protection rating, requiring installation in dry, sheltered locations.

Advanced protection circuits protect against:

• Overcurrent,
• Output short circuits,
• Interference from the power grid,
• Short voltage drops.

Switching technology minimizes heat loss and ensures the longevity of electronic components, resulting in high operational reliability.

Professional applications and installation conditions

The ZTM-60/12 model finds wide application in professional installations:

• Building automation - control of solenoid valves, electric strikes,
• Access control systems,
• CCTV monitoring installations,
• Staircase and ceiling lighting,
• Outdoor garden lighting,
• Computer and network equipment,
• Intercoms and video intercoms,
• Programmable Logic Controllers (PLC).

Installation requires SEP qualifications up to 1kV and disconnection of the power circuit using a fuse or circuit breaker. It is recommended to use a conductor with a maximum diameter of 2.5 mm² to connect the power supply.

The device complies with CE standards and holds an IP20 certificate.
