This unit is intended for use with robots from the Dolphin/Mayontronics family that require a basic power supply.
Key Features
- Output: 120 W power supply for 115-V input (100-240 V, 50/60 Hz) service environments.
- On/off operation only—no WiFi or advanced timer functions.
- Compatible with a range of Maytronics Dolphin robotic pool cleaners (models such as S50, Active 10, Echo, E10, T15, Encore, Escape, and others with basic power supply requirement).
- Genuine certified Maytronics part to maintain approved performance and warranty integrity.

Compatibility / Use Cases
This unit is well suited for robotic pool cleaning systems that originally used or require a “basic” power supply with on/off functionality (rather than advanced weekly timer or WiFi capabilities). Typical compatible robots include:
- Dolphin S50
- Dolphin Active 10
- Dolphin Echo
- Dolphin E10
- Dolphin T15
- Dolphin Encore / Escape models with basic power supply requirement
Before ordering, verify your existing power supply specs, connector, and the model number of your robot to ensure compatibility.
Installation Notes
- Disconnect the robot from the electrical supply and unplug the old power supply before beginning installation.
- Remove the previous power supply unit and note the cord/connector configuration to reuse if compatible.
- Mount or place the new unit in a dry, ventilated area protected from water and direct pool chemicals.
- Connect the DC output cable to the robot as per manufacturer instructions and plug in the AC input cord (or reuse prior cord if approved).
- Turn the power supply ON and run the unit briefly to verify correct operation—check that the robot begins its cleaning cycle and monitors for any fault codes.
Troubleshooting
-
No power to robot: Check AC line is live, verify power supply ON/OFF switch, ensure DC output connector is properly seated.
-
Robot shuts off prematurely: Verify output voltage stays within specification under load, inspect for overheating of supply unit.
-
Power supply gets very hot: Confirm ventilation around unit, ensure it’s not enclosed in a sealed box, and that it is rated for ambient temperature conditions.
Maintenance Tip
Periodically inspect the power supply unit for dust buildup, corrosion at the output connector, and secure mounting. Replace if the unit shows signs of overheating (discoloration, smell) or if the DC output becomes unstable. Keeping the power supply clean and properly ventilated helps maintain the longevity of your pool cleaning robot.
