2 Pcs AQUA-REPAIR AS32/SL32 2R025 - - AQUA-RITE GLX-PCB

Description

Replacement Thermistor
Ametherm SL32 2R025
(2 Pcs)
Common Need:
HAYWARD / GOLDLINE / AQUA-RITE GLX-PCB-RITE
This board failure is often due to the "sacrificial" destruction of the thermistor used to protect the circuit from high voltage and high current surges that could occur after a lighting strike during thunderstorms or other power surge.

2 thermistors - be ready the next time!
Normally the thermistor protects the circuit on start-up, providing a relatively high resistance (2 Ohm) at ambient temperature to limit "In rush Current", and then essentially disappearing from the circuit (0.02 ohm) when the current is near or equal the design current of 25 Amp.
The part will fail (protecting the circuit board) when a power surge (Lightning, etc.) is much greater than the power handling capability of the part.
An acceptable replacement thermistor is:
Ametherm ICL - SL32 2R025
Inrush Current Limiting (ICL) Thermistor
(2 Thermistors)
(Inrush Current Limiting Thermistors)
(Use to repair: Hayward Aqua Rite PCB (GLX-PCB-RITE) Pool Chlorinator)
Note: Either AS32 2R025 or SL32 2R025 may be used, functional specifications are the same.
The only difference in the application of the thermistors is in the sacrificial failure mode when spikes in voltage/current exceed the capabilities of the thermistor. The AS32 provides a little more energy absorption before failure.
(In most cases, like a lightning strike, both thermistors will fail and the rest of the logic circuitry will be protected.)
ICLs (Inrush Current Limiters) are a cost-effective way of limiting the inrush of current that can damage components in a switching power supply and other devices when the equipment is turned on.
