CMX820P

28.8V 3.2Ah (92.2Wh) Lithium Ion Battery (15A capable)

Status: 'Active'

The new CMX820P is a high power 28.8V 3.2Ah Lithium Ion Smart battery with a stored energy of 92.2Wh. It is designed to meet the demanding needs of medical device manufacturers and comes equipped with a level of technology and regulatory compliance that will provide the next generation of medical devices with a real competitive edge.

The latest Nickel-Manganese-Colbalt Lithium ion cell technology within the CMX820P allows it to discharge continuously at up to 15A (or 330W continuous) making it ideal for high power transportable devices - either as a primary power source or as a redundant backup supply.

The industry standard smart battery interface on the CMX820P allows a host medical device to ascertain pertinent information such as state-of-charge, remaining runtime, cycle count and serial number, all of which allow the device to provide useful real-time data to the user.

When connected to a compatible smart charger the CMX820P communicates its charging voltage and current requirements which are then provided by the charger - this system increases both safety and battery lifetime as the battery remains in control of its charging regime.

A clear 5-bar LCD display on the rear of the battery provides a quick visual capacity reference for the user so they can decide which batteries need charging and which can be used.

The CMX820P meets the requirements of IEC62133:2012 (Safety), UL62133 (Safety) and UN38.3 (transportation), meaning that that it can be quickly and easily designed into the next generation of medical devices with minimal cost to the OEM.

The CMX820P ships with Entellion branding, white casing and a standard software set-up. All of these can be customised to suit a particular OEM requirement - please contact us to discuss.
