Electrical Power Systems (EPS)

DHV Technology provides a comprehensive suite of Electrical Power Systems (EPS) tailored for various satellite platforms, from CubeSats to SmallSats. The offerings include a Power Conditioning Distribution Unit (PCDU) for SmallSats, NanoEPS for CubeSats ranging from non-deployable 3U to triple deployable 2U, 3U, or 6U, PicoEPS for 1U to 2U CubeSats, and MicroEPS for non-deployable 6U to quad deployable 3U, 6U, 12U, and 16U CubeSats.

The PCDU for SmallSats is designed for efficient power supply and control, comprising a power management module and a battery module. The Power Module manages solar panel inputs, battery charge, and HDRM control for solar array deployment, and is scalable starting at 900W. The Battery Module handles energy storage, thermal control, and circuit protection against overloads, over-discharges, over-currents, and short circuits, with capacities from 415Wh to 1660Wh.

The NanoEPS, designed for CubeSats from non-deployable 3U to triple deployable 2U, 3U, or 6U, also consists of a power management module and a battery. The Power Module manages solar panel inputs and battery charge, generating 3.3V, 5V, 12V, and VBAT power buses, including switched power lines. The Battery Module is responsible for energy storage, thermal control, and circuit protection. Key features include scalability, Maximum Power Point Tracking (MPPT), space qualification, thermal knife control, PC104 form factor, and an ISS compliant version.

The PicoEPS, for 1U to 2U CubeSats, integrates a Power Module and a Battery Module onto a single board to meet size and weight restrictions. It manages solar panel inputs and battery charge, generating 3.3V, 5V, 12V, and VBAT power buses. It’s available in two configurations: battery integrated (1400mAh capacity) and extended battery, which can increase capacity up to 2800mAh with an additional module. Highlight features include scalability, MPPT, space qualification, PC104 form factor, and an ISS compliant version.

The MicroEPS is designed for CubeSats from non-deployable 6U to quad deployable 3U, 6U, 12U, and 16U. It also comprises a power management module and a battery module. The Battery Module handles energy storage, thermal control, and circuit protection, while the Power Module manages solar panel inputs, battery charge, and generates 3.3V, 5V, 12V, and VBAT power buses. DHV Technology also offers custom product design to meet specific mission requirements.
