Chroma 62000D Series Bidirectional Power Supply**Chroma 62000D** programmable bidirectional DC power supplies provide both power source and load characteristics. These two quadrant power supplies allow power from the DUT to be converted back to the utility grid and so are ideal for testing renewable energy power systems such as PV, storage, and EV inverters as well as a wide range of bidirectional power conditioning system (PCS) and may also be used as a battery simulator. **Key Features** - Voltage rating : 0~100V/600V/1200V/1800V - Current rating : 0~540A - Power rating : 6kW/12kW/18kW - Two-quadrant operation: source and load functions - High power density: 18kW in 3U - Easy master/slave parallel - Wide range of voltage & current combinations in constant power - Auto sequencing programming - Voltage & current slew rate control - High speed transient response **Application** - Charge/discharge testing and life cycle testing, including BOBC, DC-DC conversion, and PCS - Motor driver testing for DC-AC power supply and energy feedback - Compliant with LV123 and LV148 standards on electrical car components testing - I-V power source simulation of energy storage, battery, and fuel cell in microgrid labs - Battery power simulation for testing powertrain and auxiliary systems such as electric vehicles and e-scooters, stacker trucks, and shipsmore... -
Chroma 63103A LED Load SimulatorEach 63103A load module is designed with state-of-the-art technology and connects all the power MOSFET devices in parallel to insure high accuracy load control with a minimum drift of less than 0.1%+0.1%F.S. of the current setting. Chroma's use of FET technology provides minimum input resistance and enables the load to sink high current even at very low voltages. For example, the model 63103A is capable of sinking 60A at 1V, and well-suited for testing the new 3.3V low voltage power supplies. Low voltage operation, down to zero volts, is possible at reduced current levels. Key Features ------------- - Unique LED mode for LED power driver test - Programmable LED dynamic resistance (Rd) - Programmable internal resistance (Rr) for simulating LED ripple current - Fast response for PWM dimming test - Up to eight channels in one mainframe - 16-bit precision voltage and current measurement with dual-range - Full Protection: OC, OP, OT protection and OV alarmmore... -
Chroma 61809/61812/61815 Regenerative Grid Simulator**Chroma 61809/61812/61815** models are regenerative providing a complete energy saving solution. The power generated by the DUT during the test can be easily fed back to the grid, rather than dissipated as heat, which protects the environment and lowers the cost of operation. With this capability, these models can be applied to applications in green energy products, such as PV inverters, energy storage systems (ESS), power conditioning systems (PCS), micro grids, power hardware-in-the-loop (PHIL), electric vehicle power supply equipment (EVSE), on-board charger (OBC) and bidirectional on-board charger (BOBC). **Key Features** - Output Power 61809: 9kVA 61812: 12kVA 61815: 15kVA - Output voltage: 0~350V - Output frequency: 30Hz~100Hz/DC - High Power Density 15kVA in 3UH - Intuitive Touch Panel Interface - User selectable single phase or three phase output - Full 4 quadrant, fully regenerative up to 100% of output current rating - Programmable slew rate settings for voltage and frequency - Programmable voltage and current limits - Turn on, turn off phase angle control - Synchronize TTL signal of voltage changing - LIST, PULSE, STEP mode functions for testing Power Line Disturbance (PLD) simulation - Harmonics, inter-harmonics waveform synthesizer - Comprehensive measurement capability, including current harmonics - Parallel output for higher power applications (Three phase only) Applicationmore...
