Mounting
Standard Mounting
The standard model comes with plug-in cable connectors. (See appendix for a list of
connector types)
The chassis can be mounted to flat surfaces with four #6 screws that go through four
holes in the amplifier chassis. The mounting surface may provide adequate heat-sinking,
or the amplifier can be ordered with a standard (-H option) or extended -HX option)
heatsink. (See section on cooling for heatsink recommendations)
PC Board Mounting (-P option)
This option changes the connectors from plug-in cable connectors to extended male pins.
These pins permit either soldering directly into p.c. boards, or can plug into spring-
loaded pin sockets like the ones used on the MB4 and Eurocard. Part numbers for these
pin-sockets are listed below:
Connector Pin-Socket
22 pin signal connector AMP: 50864-5
4 pin power connector AMP: 1-50871-0
When mounting on p.c. boards, consider the airflow across the amplifier and ambient
temperature to determine if a heatsink is required.
MB4 Card Mounting ( -M option)
The MB4 mounting card must be used with amplifiers ordered with the -P option. The
card pushes onto the pins in a piggy-back fashion. Thereafter, connections are made to
the MB4 card which connects to the amplifier via the pins.
A Current-limit trimpot is standard on the MB4 card, as are Balance, and Feedback
(internal loop-gain) trimpots.
The MB4 provides additional functions not available on the standard amplifier. These
are:
Voltage-Mode operation with IR compensation (-V option)
PWM Inputs (-P option)
Edge Filters (-F option)
See section on MB4 card for additional information.
Eurocard Mounting (-E and -ER options)
A 3U x 10HP extended Eurocard mount (220 mm) is available with (-ER option), or
without (-E option) a front panel. Trimpots are accessible from the front panel, as are the
current monitor output, status LED, and Reset push-button switch. Power and signal
connections are all made via a DIN 41612 type “D” connector on the backplane end of
the card.
