Power adapter/inverter MEAN WELL DETN02L-15, 2 W, input 4.5–5.5 V, output 15 V, RoHS

MEAN WELL DETN02L-15 is a compact PCB-mount DC‑DC converter/inverter designed for low‑power applications. The module accepts a 4.5–5.5 V DC input and provides dual symmetric outputs of ±15 V at approximately ±0.067 A (total output power 2 W). Packaged as an SMD device with a shallow 15.2 mm depth and built to RoHS standards, it is intended for embedded electronics, industrial modules and small equipment that require reliable low‑power bipolar rails from a single 5 V supply.

Advantages

The converter delivers stable dual ±15 V outputs from a low-voltage input in a small surface-mount form factor, enabling compact PCB layouts and automated assembly. Its short-circuit protection (0.5 second) helps protect connected circuitry from prolonged faults, while RoHS compliance supports environmental and regulatory requirements. The low-power 2 W design minimizes thermal dissipation and is suitable where space and heat budget are constrained.

Suitable for

• Embedded systems and microcontroller boards requiring bipolar analog rails
• Sensor modules and signal-conditioning circuits
• Small industrial control modules and communication devices
• Portable instrumentation and compact test equipment

How to use

Mount the SMD converter on the target PCB according to the manufacturer's recommended footprint and soldering profile. Apply a regulated DC input within 4.5–5.5 V and verify correct polarity before power-up. Connect the bipolar outputs to the load, respecting the ±15 V polarity for analog or signal circuits. Follow good layout practices: place input decoupling capacitors close to the converter input pins and route output traces to minimize noise coupling to sensitive circuitry. Allow adequate airflow or thermal paths if the module will be operated near its maximum power rating.

Recommendations

For reliable operation, use a stable 5 V supply and ensure that connected loads do not exceed the rated current per rail. Implement input filtering and adhere to the recommended PCB footprint and soldering guidelines. If the converter will encounter frequent short events, evaluate system-level protection to prevent repeated stress on the module.
