Description

The UPS25ER is a flexible PC/104 uninterruptible power supply subsystem that is designed to work together with the RTD XPWR104 power supply Peripheral Module to form a reliable power supply system. This scheme will allow main power interruption up to 30 minutes at 20 Watts while still maintaining complete computer operation.

The main input is rated from 10 to 40V DC for the UPS25ER unit. While the supply is over 10V the UPS25ER will charge the local backup NiMH/NiCd battery pack using one of the available charging modes. These charge modes are automatically controlled by the onboard charger circuitry. The charging of the batteries can be enabled from your application software. Additionally, the software can interrogate the UPS status and power states at any time. The UPS25 routes power to your power supply module from either the main input or from the backup battery during main input power failure. An interrupt can be generated when the main power fails, and there is also a status bit that will indicate a soon-to-be discharged battery.

The UPS25ER features a unique shutdown mode where your application software can disconnect the UPS battery after it is ready to shut down. After the UPS25ER is put to sleep the backup battery is disconnected to save the backup battery from being unnecessarily discharged.

The charging unit on the UPS25ER ensures that maximum battery life is achieved. The onboard NiMH/NiCd charger accepts 8 batteries with a maximum capacity of 1500 mAh. The nominal full battery voltage is approximately 11.5V while a completely discharged battery pack will give 7.5V. Battery temperature is used to terminate the charge process as well as to protect the battery from being charged outside the recommended charge temperature range of 0 to +40C. NiMH batteries will provide
