UPS System IP Case Ratings

IP is a numeric system for describing the Ingress Protection provided by a case around a piece of electronic equipment from both solid objects and liquids. The system was established by the International Electro Technical Commission, under EN60529. The larger the value of each digit, the great the degree of protection provided.

In general, UPS systems have an IP rating of 20 (IP20) but occasionally we are asked for higher IP ratings and most commonly IP54. Typically IP20 is suitable for office environments, comms rooms and data centre environments. IP54 is more suited to industrial and more extreme environments where there may be wider temperature ranges, moist/wet conditions, dirt, dust and other environmental factors that the UPS system must be protected from in order to deliver a guaranteed performance.

It may not always be possible to uplift an IP-rating for a UPS system due to airflow, dust filter and heat considerations. In this case, we can quote for a specially manufactured or modified enclosure for the UPS system. Larger containers can house both the UPS system and a standby generator, air conditioning, lighting, solar PV array and associated LV switchgear.

IP Rating Table

IP Rating Ingress of Solid Objects (1st digit) Ingress of Liquids (2nd digit)
0 no protection no protection
1 protected against solid objects over 50mm eg hands, large tools protected against vertically falling drops of water or condensation
2 protected against solid objects over 12.5mm eg hands, large tools protected against falling drops of water, if the case is disposed up to 15degrees from vertical
3 protected against solid objects over 2.5mm eg wire, small tools protected against sprays of water from any direction, even if the case is disposed up to 60degrees from vertical
4 protected against solid objects over 1mm eg wires protected against splash water from any direction
5 limited protection against dust ingress (no harmful deposit) protected against low pressure water jets from any direction – limited ingress permitted
6 totally protected against dust ingress protected against high pressure water jets from any direction – limited ingress permitted
7 protected against short periods of immersion in water
8 protected against long, durable periods of immersion in water
9 protected against close-range high pressure, high temperature spray downs

IP54 UPS Enclosures

At EcoPowerSupplies we specialise in both standard IP20 and higher-rated IP UPS systems. We can provide 19inch rack mounted high IP-rated enclosures and AC UPS systems and DC Power systems (floor standing or wall mount) to IP54 in a range of sizes and finishes to suit your application and environment. We can also source Stainless Steel Cabinets for use in clean environments such as the pharmaceutical industry and saline installations.
