6EP1352-1SH03

What does this power supply do?

This unit is a stabilised DIN rail power supply designed to convert a wide AC or DC input into a regulated 15 V DC output. It is intended for industrial control and panel applications where a consistent low-voltage DC supply is required.

What input voltage range can it accept?

It is designed for wide-range operation and accepts 85 to 264 V AC at 47 to 63 Hz, or 110 to 300 V DC. This makes it a practical choice for installations that need flexibility across different mains conditions.

What output does it provide?

The unit provides a regulated 15 V DC output with a rated current of 4 A, giving a typical output power of 50 W. Siemens 6EP1352-1SH03 is suitable for applications that need a stable 15 V supply for industrial electronics and control devices.

Is the output voltage adjustable?

Yes. The output voltage can be adjusted using a potentiometer, with an adjustment range of 10.5 to 16.1 V DC. This can be useful where a small amount of voltage trimming is needed to match the connected load.

How is the unit mounted?

It is designed to snap onto a standard DIN rail in accordance with EN 60715 35 x 7.5/15. This makes installation straightforward in control cabinets and electrical enclosures.

What are the overall dimensions?

The enclosure is approximately 72 mm wide, 90 mm high and 52.6 mm deep. Its compact format helps when panel space is limited.

Can multiple units be connected in parallel?

Yes. The power supply allows parallel connection for increased performance, with up to two units able to be connected in parallel where the application requires additional output capacity.

What protection features are included?

The unit includes output overvoltage protection, current limiting and short-circuit protection with a constant current characteristic. It is also designed with primary-to-secondary isolation and provides a safety extra-low output voltage in line with the stated standards in the datasheet.

How efficient is the power supply?

At rated output voltage and current, efficiency is approximately 85%. Typical power loss at full load is around 11 W, while maximum no-load power loss is 2.3 W.

What environmental conditions is it designed for?

It is rated for operation from -20 to +70 °C with natural convection. From +55 to +70 °C, derating applies at 2% per kelvin. The unit also has an IP20 degree of protection and is intended for installation in a suitable enclosure.

Does it include a status indication?

Yes. A green LED indicates that the output voltage is present and within the expected range, giving a simple visual confirmation during operation.

What type of terminals does it use?

The unit uses screw-type terminals. The input terminals are provided for L and N, and the output includes positive and negative terminals, each suitable for conductors from 0.5 to 2.5 mm².
