DIN rail power supply 120W 12V 10A SDR-120-12

High-efficiency power supply for DIN rail

The SDR-120-12 switching power supply is a reliable energy source, ideal for industrial applications and automation. Designed for DIN rail mounting, it provides convenient installation and space saving. Power of 120W and output voltage of 12V with a current of 10A make it a versatile power solution.

Safety and protection

The power supply is equipped with comprehensive protections, protecting both the unit itself and the devices connected to it. These include:

• Overload protection – prevents damage caused by excessive power consumption.
• Short-circuit protection – immediately cuts off the power supply in the event of a short circuit.
• Over-temperature protection – protects against thermal damage by limiting power or shutting off the power supply.
• Overvoltage protection – minimizes the risk of damage caused by sudden voltage surges.

Additionally, an LED indicator informs about the correct operation of the power supply, and a built-in DC OK relay connector allows for remote monitoring of the power supply status.

Efficiency and construction

The SDR-120-12 is characterized by high efficiency, reaching up to 91%, which translates to lower energy consumption and less heat loss. The active PFC (Power Factor Correction) function improves the quality of the drawn current, reducing interference in the electrical network. The power supply is adapted to work in a wide temperature range (from -25°C to +70°C) and can be peak-loaded up to 150% of its power for a short time (3 seconds), which is particularly useful when starting devices with motors or other elements with high inrush current. Compact dimensions (40x125.2x113.5mm) make it easy to install even in tight spaces. This makes it suitable for both control cabinets and electrical switchboards.
