This guide provides information on how to successfully integrate the micro

 2LP power supply into your system and how to take advantage of its features and flexibility. It is strongly recommended to familiarize yourself with this guide before connecting or powering on your unit.

Below are the manufacturer part numbers for mating connectors and pre-terminated wires needed to connect to the input and outputs of the micro

 2LP. Weight can be minimized by fine tuning the wire size based on system current draw.

Bus Input Mating Connector Housing - Molex 2064610400

Bus Input 16 AWG Pre-terminated Wire - Molex 0367693064 (x4)

Output Channel Mating Connector Housing - Molex 5031490800

Output Channel 24 AWG Pre-terminated Wire - Molex 2157111124 (x4 Black) and Molex 2157112124 (x4 Red)

The following communication checks should be performed on a new system:

Before use, configure the output voltage and power-on behavior of each output channel using the quick start guide within the Hargrave Configurator Tool.

Enable the CAN terminator on the unit furthest away from flight controller if no other CAN devices are terminating the bus.

The following mounting checks should be performed on a new system:

Ensure the power supply is mounted securely to the vehicle.

Ensure all connected cables are externally strain-relieved 

Ensure the power supply is mounted in a location with appropriate environmental protection.

Activation of protection mechanisms may cause unexpected system responses, including outputs disabling. It is important to understand these behaviors and configure them based on your application. In particular, if micro

 channels are used for flight critical power rails ensure there are no protections enabled and set to levels that may disable the channel. More information is available in the Protection Systems section.

 is to have all output channels switched off on power up. In order to use the device, at a minimum:

The desired channel voltages must be configured, AND

The “Power On At Startup” flags must be set for the desired channels or the channels must be enabled during operation via CAN.

Refer to the wiring diagram for identifying channel output and wiring polarity. During initial integration it is recommended to confirm correct voltage setting with a multimeter before connecting to your system as incorrect settings can damage downstream devices.

To configure the unit, power must be provided on the input connector and a CAN adaptor connected to the CAN connector. Further details are provided in the settings section.

 2LP can be ordered with 2 low voltage channels, 2 high voltage channels, or 1 of each. Low voltage channels can be software configured to output at one of eight discrete voltages between 3.3 to 12 V. Similarly, high voltage channels can be configured between 12 to 28V.

Variant C - Has channel 1 as high voltage and channel 2 as low voltage.

The output voltage of each channel can be configured via the CAN interface. The selectable voltage options are:
