o The use model of PB 1.5 is slightly different; users who are familiar with existing PB
1.0 please read this document fully before working with PB 1.5.
o Input power connections (from DC plant) are the same.
o Output power connections (to lower OVP) are the same, now with greater flexibility.
Definitions
OMM Output Management Module: uppermost 1U of PowerBoost, has 16 output circuit
breakers
Orion Controller: In PowerBoost upper shelf at left side; has touch screen, has Ethernet GUI
OVP - Over Voltage Protection: generally refers to the Raycap units upper and lower. Note:
the Raycap OVP units also provide a telemetry function that communicates upper channel
Voltages. This is used by PowerBoost to regulate Voltage at load.
PB: PowerBoost product
PB-COM: Circuit board at rear of PowerBoost upper shelf; interface between Raycap RS485 data
and Orion controller. Has heartbeat LED and other indicators.
RRH - Remote Radio Head: i.e., the load, typically connected near upper OVP unit)
SYS-8: Short-hand reference to PB-19-SYS-8
SYS-16: Short-hand reference to PB-19-SYS-16
General overview
JMA PowerBoost is a rack-mounted voltage boost unit that maintains acceptable voltage at the
RRH by sensing system characteristics and adjusting its output voltage accordingly. PowerBoost
makes use of telemetry data from suitably equipped Raycap OVP units as a reference point for
maintaining RRH Voltage. The PowerBoost unit is comprised of the following:
• Rack frame (19 inch 1U high), holds an Orion controller and up to 4 boost modules (2
channels per module), referred to as “boost rack.”
• Rack frame (19 inch, 1U high), holds 16 individual circuit breakers for boost outputs,
referred to as OMM output management module.
