62060D-100

Programmable Bidirectional DC Power Supplies with both Power Source and Load Characteristics

Capable of feeding power from the device under test (DUT) back to the utility grid, these two-quadrant power supplies are ideal for testing energy storage systems in renewable energy applications such as solar PV/storage hybrid inverters, battery power conditioning systems (PCS), and simulating charging and discharging of energy storage batteries.

The Chroma 62060D-100 (part of the 62000D Series) also has applications in testing power components in electric vehicles (EVs) as well as bidirectional on-board chargers (BOBC), DC-DC converters, and DC-AC motor drivers, enabling bi-directional power conversion simulation tests without the need for actual batteries.

Traditional DC power supplies need protection diodes to prevent back EMF from damaging the power supply during motor testing. However, Chroma 62000D bidirectional DC power supplies can drive the motor and also efficiently regenerate EMF to the grid, avoiding the need for blocking diodes while saving space, energy, and configuration effort.

In addition, the fast transient response of the 62060D-100 enables seamless quadrant changing in less than 1.5ms (-90% to +90% load).

The 3U models come in single-unit output power ratings of 6kW/12kW/18kW, while the 4U models have single-unit output power ratings of 36kW/45kW. The 62000D-HL model features unique dual-range output capability, allowing a single unit to provide both High (2000V/60A/45kW) and Low (650V/180A/45kW) output ranges. This enables the unit to meet high-current, full-power test conditions of the DUT while also meeting high-voltage, full-power test requirements, suitable for wide-ranging testing needs such as the 400V and 800V battery platforms used by EVs and EV supply equipment (EVSE).

The 62000D series supports up to 100 programmable sequences through its List Mode feature. Its fast transient response time meets many testing needs, including those defined in the LV123 and LV148 standards for EV components. When used with Chroma’s Softpanel software, users can conveniently conduct complex tests with a simple press of a button.

The 3U models have a universal 200- 480Vac input voltage, and the 4U models have a universal 380-480Vac input voltage. All units have active PFC low current harmonic feedback, which significantly reduces electricity costs and power system configuration in high power test environments, lowers test environment temperature, and is suitable for power systems in all regions globally. Various control methods are available, supporting digital USB/LAN/CAN/GPIB interfaces and analogue APG interface control, with the 2000V models additionally supporting CAN FD.
