3.0 IC650 Charger Operations
The Delta-Q IC650 Industrial Battery Charger is a
650-watt intelligent, programmable power device
designed to reliably charge your machine’s batteries
in the harshest of environments. It is intended to
be installed on-board or o-board and, if desired,
can be fully controlled by your own machine
control module. The charger also provides electrical
protection to help maintain the integrity of your
vehicle’s electrical system and protect your users.
3.1 Overview
As an advanced power conversion device, the
Delta-Q IC650 Charger eciently provides
clean DC output in a very compact package. It
does this using a small, light, high-frequency
switching transformer while still incorporating
a utility-friendly power factor correction stage.
The charger’s overall design is also optimized for
maximum ruggedness and reliability to provide
many years of service.
Isolation
Delta-Q has developed an innovative system of
isolation boundaries to separate the IC650 Charger’s
advanced features into four galvanically-isolated
electrical domains:
i. AC Input: Isolated input to AC source (0-270VAC)
ii. DC Output: Isolated output to batteries (0 V - 3
Vpc DC)
iii. LV: Isolation for USB and other signals (0-5V DC)
iv. ELV: Isolation for CAN bus (0-5 VDC)
Congurations
The Delta-Q IC650 Charger has two primary
congurations. The only dierence between the
models is the inclusion of a communication port
on the “Comm” model for the purpose of advanced
control communication.
1. Comm: Full CAN bus control and other signals
available.
2. Base: Base model connections to the battery
and controller interlock.
Either of the above can be congured for on-board
or o-board use. For more details, please see the
“Electrical Installation” section of this design guide.
