Available from Server Room Environments including single phase and three phase outputs for the protection of server rooms and small datacentres. The UPS are rated at 20kVA and the kW-rating will vary depending on the output power factor of the UPS. The UPS may offer parallel capability allowing two or more UPS to be configured for additional resilience into an N+X configuration. The range includes options for internal batteries and external battery extension packs to extend the amount of runtime available.
Transformerless UPS operate can operate at high operating efficiencies over a wide load range (down to 25% typically) and are designed for server room and datacentre environments. Where Galvanic isolation is required the UPS can be installed with a separate isolation transformer in a side cabinet. Transformer-based UPS include a Galvanically isolating transformer as part of their design and are constructed for harsher electrical and more industrial environments.
Please contact us if you need more information on the differences between the two on-line UPS technologies.
Server Room Environments provides a complete electrical installation service for 20kVA/20kW UPS systems by NICEIC certified electrical contractors. The installation service covers every aspect you could need in a UPS installation including:
UPS battery runtime is dependent upon several factors including load size, battery charge percentage, battery age and ambient temperature. Our project managers can provide a calculated battery back-up time for your load and UPS system. The standard UPS battery is a valve regulated lead acid (VRLA) type with options for lithium-ion batteries available.
A UPS maintenance contract is recommended with an annual preventative maintenance visit for this size of UPS system. The maintenance contract will include technical support, parts (excluding consumables) and labour and an emergency call out facility. The call out server levels include 4 clock hours, 8 working and 12 working hours.
