Description:
The SixPacTM from Applied Power Systems is
a configurable IGBT based power stage that is
configured as a half-bridge for many high
power applications. The IAP900D120 and
IAPL900D120H can be used as a chopper for
motor braking or two can be used in a full-
bridge inverter application. Three
IAP900D120s or IAPL900D120s can be used
as a three-phase inverter.
The semiconductor modules are mounted on
a forced air-cooled or water cooled heat sink.
The switching devices interface with a
capacitor bank via a low inductance laminated
bus. The gate drive board provides a simple
user interface along with protection features
including: overvoltage, overcurrent,
undervoltage lockout, overtemperature, shoot-
through, and short circuit protection.
Depending on application characteristics, the
SixPacTM is suitable for operation with DC bus
voltages up to 800 VDC and switching
frequencies above 10 KHz.
Features:
• High performance IGBT inverter bridge
• Integrated gate drive board with fault
monitoring and protection
• System status / troubleshooting LEDs
to verify or monitor proper operation
• Isolated, low level (50:1), analog
feedback of DC bus voltage
• Isolated gate drive power supplies
• Low inductance laminated bus
• Output current measurement and
feedback
• Superior short circuit protection and
shoot through prevention

NOTES:
1. Open collectors can be pulled up to 30VDC Max and sink 50mA continuous.
2. DO NOT connect a 15VDC and 24VDC source to the unit at the same time. Use one or the other.
3. GND signals to be used for analog feedback signals, i.e. twisted pair with IOUT Phase A.
4. The error signal on pin 5 is the ORed output of the OverVoltage, OverTemp and UVLO fault signals. An
LED will illuminate on the board to differentiate specific faults.
5. The gate drive board can be configured with a 16 pin connector, Consult APS engineering for more
details.
