Frequently Asked Questions

What is a DC to DC converter used for?

A DC to DC converter steps down or steps up DC voltage. In EVs and golf carts, it's often used to reduce high battery voltage (e.g., 48V) to 12V for powering lights, radios, and other accessories.

Can your chargers work with lithium batteries?

Yes, our 12V 4A chargers are compatible with both lead-acid and lithium batteries, with appropriate charging profiles to ensure safety and longevity.

Do you offer custom voltage or power ratings?

Yes, as an independent R&D manufacturer, we can customize voltage input/output, power ratings, and physical dimensions based on your requirements.

Are your products certified?

Yes, our products have passed CE and RoHS certifications. Our company is also ISO9001 certified for quality management.

What is the working voltage range of your 24V-96V to 12V converter?

The input range is 24Vdc to 96Vdc, making it suitable for a wide variety of electric vehicles and industrial applications.
