D36V28F12 inverter outputs
| Pin | Description |
|---|---|
| VIN | Input voltage. |
| GND | Mass potential. |
| VOUT | Output voltage. |
| ENABLE | The low-voltage state (below 1 V) will cause the system to go into a low energy consumption state (approx. 10 μA). The pin is pulled to the supply voltage through a 270 kΩ resistor, which makes the system switched on by default. |
| PG | Pin "Power Good" open-drain. It goes into a low state when the output voltage drops below 85 % of its nominal value. If this pin is used, a pull-up resistor, e.g. 10 kΩ, must be connected. |
The module has six described connectors with a 2.54 mm grid. The inverter can be plugged directly into thecontactboard,wired orsoldered intoa dedicated PCB.

The efficiency graph of the system.
Inverter system efficiency
The module has a very high efficiency of 90% - 95%. Efficiency is defined as the ratio of output power to input power (Power out)/(Power in). This is a very important parameter in the case of work with portable power sources, where the time of operation on one charging cycle counts.
