ADC Variable Series – ADC4370, ADC7520 and ADC7480
Chassis Mount Variable Power Supplies
The ADC variable series is a part that we have been providing for many years. As a small unit, with a high degree of adjustability, we’ve found that these units are popular across many industries due to it’s simplicity and easy to use variable outputs. For requirements that need a simple output adjustment without the full solutions offered by a programmable power supply, these meet a nice balance of practicality and affordability.
Product Selector
The ADC units have nominal output voltages, that are adjustable above this. Whilst there is derating above certain voltages (more information in the datasheet), the output adjustability is listed as below, with a link to the product page.
ADC4370 – 800W Modules
| Part Number | Output Adjustability |
| ADC4370/12 | 0-18Vdc / 0-50A |
| ADC4370/24 | 0-36Vdc / 0-30A |
| ADC4370/36 | 0-54Vdc / 0-20A |
| ADC4370/48 | 0-72Vdc / 0-15A |
| ADC4370/72 | 0-108Vdc / 0-10A |
| ADC4370/96 | 0-144Vdc / 0-7.5A |
ADC7520 – 1600W Modules
| Part Number | Output Adjustability |
| ADC7520/24 | 0-36Vdc / 0-60A |
| ADC7520/36 | 0-54Vdc / 0-40A |
| ADC7520/48 | 0-72Vdc / 0-30A |
ADC7480 – 3000W Modules
| Part Number | Output Adjustability |
| ADC7480/12 | 0-18Vdc / 0-200A |
| ADC7480/24 | 0-36Vdc / 0-127A |
| ADC7480/36 | 0-54Vdc / 0-95A |
| ADC7480/48 | 0-72Vdc / 0-64A |
| ADC7480/72 | 0-108Vdc / 0-42A |
| ADC7480/110 | 0-165Vdc / 0-25A |
| ADC7480/160 | 0-230Vdc / 0-20A |
| ADC7480/220 | 0-320Vdc / 0-14A |
Unfortunately there are a number of units which were made obsolete from the ADC7480 range. We can offer alternatives still, and due to the nature of the ADC range, we can even offer alternatives by Powernet.
Optional Accessories and Upgrades
The ADC series is available with a number of options and accessories that adds more features or changes to the units. To add the accessory to the unit, you simply add the required part to the end of the unit. For example, if you require the Analogue Interface version of the ADC4370/96, you would order the ADC4370/96AI.
| Accessory Part Number | Definition |
| H | Trimmer adjustable model with power fail relay alarm |
| AI | Analog controllable model by external 0-5Vdc |
| AIH | Analog controllable model with power fail relay alarm |
| TH | Temperature compensation model with power fail relay alarm |
Alongside the options above, we can offer the ADC range as a master and slave configuration for larger output powers.
Part Numbers Explained
As we’ve been fortunate to provide these units for many years, that part number provided has been changed a few times over the years. Whilst you may see PowerNet written on one of the units, this is the original name of the manufacturer that is now Enedo. So a PowerNet ADC4370/96 will be the same as an Enedo ADC4370/96.
Sometimes you may see a unit written as ADC4370/96-1, which means it’s a revision 1 model. Over time the unit is upgraded with more advanced electronics inside, but the unit you order will still have all the capabilities and features you expect.
Finally, we provided the ADC as a rebadged Zentro-Electrik part for a number of years. These were sold as the ZAT series, and whilst they are the exact same unit, there can be some confusion when looking for an updated or replacement unit. To help, we have made the following table with more information.
