Replacing a MagneTek or Parallax 3200 Series System.
3200 Series Linear converter/chargers were manufactured with several different options
available and
option codes
after the model number were used to identify these different
configurations.
Example:
32 40 PX
Series
DC amperage output
Options
Later production units (out to the end of production) reduced
available options to basically two, option
P
and option
X
.
The two questions that need to be answered about a 3200 series
converter/charger requiring replacement are:
1. Does it have the internal Fuse Block? Option B or T
2. Does it have the 120-Volt Cord Set? Option X
The recommended replacement for any 3200 Series
converter/charger is a Parallax Power Supply 7400 series
deck mount converter/charger.

Choose an appropriate DC amperage output comparable to the original 3200 series DC output
amperage. Installing a 7400 series with a higher DC amperage output is acceptable, but be aware
that this may also require upgrading the battery bank wiring and the battery over-current
protection fuse or breaker to prevent nuisance battery breaker tripping. Upgrading the battery
wiring and battery over-current protection is recommended when increasing the DC amperage
