PULS Power Supplies

More Information about PULS Power Supplies

PULS DIN rail power supplies have product families that include: PIANO, DIMENSION, MiniLine and FIEPOS.

PIANO Power Supplies

The PIANO power supplies are suited for a wide range of economical applications from 36 to 480 W with high-efficiency, long lifetime and a compact design.

DIMENSION Power Supplies

More demanding applications can utilize the fully-featured DIMENSION products. They include the widest range of 12 to 48 V DIN rail power supplies which are classified in three series: Q, C and X with 1, 2 or 3 phase input and a power of 80 to 960 W.

Miniline Power Supplies

The MiniLine power supplies are best for low and medium power range applications from 15 to 100 W. The units are reliable, efficient, compact and can be installed in seconds.

Field Power Supplies

The decentralized FIEPOS field power supplies with high protection classes were developed for use directly in the field. The 300W and 500W field power supplies fit in an efficient and compact housing.

FAQs 

Does PULS carry DC power products?

Yes. PULS offers a range of DC power products in addition to its AC/DC power supplies. These DC power products include DC/DC converters and DC UPS systems.

Does a PULS product come with technical support?

Yes. PULS provides technical support for its products to help customers with any questions or issues they may have through a variety of channels, including phone, email, and online resources such as user manuals and datasheets.

Which PULS power supply has the longest service life?

PULS offers a wide range of power supplies, and the service life of each product can depend on various factors such as operating conditions, environment, and maintenance. One example of a PULS power supply with a particularly long service life is the PULS QS20.241. It has a predicted service life of up to 1 million hours (approximately 114 years).

What are redundancy modules?

Redundancy modules are installed in parallel with the primary power supply, and they monitor the output voltage of the primary power supply. If the voltage of the primary power supply falls below a certain threshold or fails completely, the redundancy module automatically switches over to the secondary power supply.

How to Select and Size a Power Supply

A power supply alters power from one type to another and ensures that the voltage being delivered is the proper level, with the right characteristics, to enable equipment to function properly.

Power rating 

If a power supply is rated for 5 amps at 24 VDC, (where voltage times amperage equals total wattage) the power rating for that power supply is roughly 120 Watts. This rating is very important because if this number is exceeded, it can cause a failure of the power supply and potentially damage other hardware wired downstream or on the load side of the device. To avoid this failure is important that the power supply is sized correctly. 

Sizing a power supply

To properly size a power supply, identify what devices will be reliant on the power supply and what their total power consumption will be. The sum of all power to be delivered needs to be less than the total power rating of the power supply. For example, if the devices combined for a total of 100 Watts, then a 5 AMP power supply, which is rated for up to 120 Watts, would be sufficient. However, if the sum of those devices' total power requirement is greater than that of the power supply rating, then a different power supply should be selected. It is important to allow for a buffer or safety factor. When sizing a power supply, never select a power supply that is rated for the same amount of power as the total power requirement of all of the devices. Oversizing the power supply will allow for changes and additions that may occur in the future.
