This 24V to 36V linear battery charger is long overdue. While this is an old circuit technique, it is optimized for charging higher voltage lead-acid battery packs, and could be used on other types of ...

Phoenix Contact has two new DC-DC transformers rated at 24V/1A in its Mini Power power supply range. They transform direct voltages ranging from 36 to 74V (or 10 to 32V for the second DC-DC ...

So a 40VA, 24V transformer can only carry 1.67 amps of load. In many cases, you will need to add another 24V transformer to carry the load of accessory components. In 24V controls, electromagnetic ...

Both standard and low-profile power transformers have been developed for 24V primary uses, such as HVAC and various instrumentation applications. The low-profile SLP-24-050 through SLP-24-300 ...

I don’t get why he uses an opto isolator. Isolation from the main is already done through the 24V transformer. A driver made with a 2n2222 and 2n2907 is enough too.
