What UPS Accessories Should I Consider?
The most commonly purchase accessories for a UPS include the following:
- UPS Software and Monitoring Apps: this is the most commonly selected for clients who want to monitor their UPS remotely and/or configure an automatic shutdown of their connected loads. The software is generally available for download from the relevant UPS manufacturer’s website.
- Interface Card: plug-in cards are available for UPS systems with an appropriate communications slot. Cards include SNMP, signal contacts and Modbus.
- UPS Maintenance Bypass: this is an external device, either wall mounted or rack mounted that allows the UPS system to be bypassed for maintenance, service or removal. The bypass will use either plug-in (3kVA UPS and under) or hardwired (above 3kVA) connections.
- Power Distribution Units: PDUs provide additional outlets and way to distributed protected power paths within a server rack. For installations with A and B power supplies, the PDUs will be connected to one or more UPS systems.
- Automatic Transfer Switches (ATS): also referred to as an STS (static transfer switches), powers connected loads from one of two power sources. These can be two UPS systems or a combination of one UPS and one mains power supply. The ATS/STS increase the resilience of the UPS installation by providing a redundant power path.
Please refer to each UPS product page and the related products tab, brochures or data sheets for a list of the available UPS accessories available.
