Frequently Asked Questions
Can the J300V4.5A13 run on 110V AC?
The listed input range is 200–240Vac at 47–63Hz. 110V AC is outside that range; check your supply voltage and the unit label before installation.
What is the maximum output power?
The J300V4.5A13 is listed at 300W maximum output power. Confirm the required output voltage and current separately when checking compatibility.
How much mounting space does it need?
The enclosure measures 190 × 82 × 30 mm. Allow for the installation’s mounting arrangement, wiring access and ventilation requirements.
What cooling method and operating temperature are listed?
The specification lists natural cooling and a working temperature range of −30°C to 60°C.
Is the 0.50 power factor an efficiency rating?
No. The listed 0.50 at 230Vac is the power factor, not a conversion-efficiency percentage. This listing does not provide a conversion-efficiency value.
