Often times, existing sites are the locations with the most need for added monitoring, but are often the hardest to modify. The 5210 DPM has the flexibility to allow installation in numerous environments. The 5210 can be installed or retrofitted into new or existing Transfer Switches or switchgear..

Additionally the 5210 can be purchased pre-mounted in a wall mount enclosure for monitoring third party equipment, or as a loose meter for integration into other systems.

Regardless of where it is installed the 5210 will provide the needed data to allow knowledgable and insightful decision making on a daily basis.
