The PRX is a complete, uninterruptable power management system on a single board. It combines an input power control unit with four battery chargers and a buck-boost output regulator. When external power is present, the system automatically charges the battery pack(s) while supplying a regulated output voltage (which may be above, below or equal to the battery voltage). Regulated output voltage can be adjusted on-the-fly. When external power is removed, the system seamlessly switches to battery operation and continues to supply the regulated output voltage. When external power is restored, the system seamlessly reverts to input power and recharges the pack(s). When configured with multiple packs, the packs are all hot-swappable.
Key Features:
- Up to four hot-swappable 5A SMBus battery charging channels
- Buck/Boost regulated output power voltage
- Buck/Boost input power voltage
- Onboard and remote capable LED indicators
- I2C and UART communication capabilities
- Layout and configuration customizable
The PRX displays its present status via five onboard, bicolor LEDs. There is one LED for each battery pack and one for the overall system. For convenience, all the LEDs may be externally mirrored, and all status information can also be read electronically via I2C link. Additionally, status information is broadcast periodically on an UART link (output only).
The PRX supports all common battery chemistries including lithium ion, lithium polymer, lithium iron phosphate, nickel metal-hydride, nickel cadmium and lead acid. It handles both smart and dumb battery packs.
This series of battery chargers consists of the following models:
- PRX-5001
- PRX-5002
- PRX-5004
