Question
How is the PTC10K-SL different from the PTC10K-CH?
Answer
The PTC10K-SL is a specially designed “booster” unit for the PTC10K-CH. By using the two products in a master/booster configuration, the maximum output current doubles to ±20 Amps.
To double the output current, the configuration requires a master (PTC10K-CH) unit and a booster
(PTC10K-SL) unit. The master unit cannot be used as a booster. The booster is not designed for standalone operation.
Without the “master” control portions of the unit installed, the PTC10K-SL provides a lower-cost solution for applications where a higher current output is required.
The PTC10K-SL does NOT have the following parts installed:
- J1 connector (includes Sensor+ and Sensor- connections)
- J3 connector (includes connections for Enable, Common, Act T Mon, Set T Mon, Common, Ext T Set)
- Output Enabled LED
- Temp Set Trimpot
- PGAIN Trimpot
The PTC-10K-SL units can be identified on the cover by the serial number found underneath PTC10K-CH. “SL” will always begin the serial number on the booster units.

The WCB501 cable connects the PTC10K-SL to the PTC10K-CH.
