HDL3000 Series AC/DC Power Supplies

XP Power’s HDL3000 high-efficiency 3 kW AC/DC power supply series covers nominal outputs from 12 V_DC to 400 V_DC. All models offer both output voltage programming from 0% to 105% and output current programming between 0% and 105%. Programming is available via I²C bus, voltage (analog), or resistance.

With power up to 3,000 W, and higher voltage outputs, the flexibility of the HDL3000 can serve a multitude of applications where a controllable, high-power capability is required: such as battery simulation, automation, robotics, lasers, electro-plating, cathodic protection, test and measurement, and specialist LED heating/curing.

Each unit also has a user-selectable auxiliary 5 V / 0.5 A or 9 V / 0.3 A standby output. The nominal output voltage can be trimmed ±5% by an internal potentiometer in addition to the voltage programming function. For higher current requirements, up to five units may be connected in parallel with active current sharing.

The built-in I²C interface enables serial data commands to monitor and control the power supply. Functions include, enable, current share, V program, I program, and 5 V / 9 V standby. An LED indicator on the unit front also provides visual indication of DC OK, output inhibited, output overvoltage, output overload, overtemperature, fan fail, and 5 V/9 V standby fail.

The input-to-output isolation is 3 kV_AC, input-to-ground 1.5 kV_AC and output to ground 0.5 kV_AC. The single-phase input voltage range is 90 V_AC to 264V_AC. When operating at low-line (<180 V_AC) output power is limited to a maximum of 2 kW, while operating at high-line (180 V_AC to 264 V_AC) provides a maximum output power of 3 kW with 93% efficiency under high-line/full load conditions.

Standards include EMC emissions: EN55032 Class A for conducted and radiated; EMC immunity: EN61000-4-2, 3, 4, 5, 6, 8, and 11. Safety approvals include: IEC-60950-/IEC62368-1, UL60950-1/UL62368-1, and EN60950-1/EN62368-1. All models feature a comprehensive set of protection features including over-temperature, overload, overvoltage, and short-circuit.

The unit utilizes forced-air cooling with intelligent fan speed control to minimize audible noise while offering an operating temperature range from -20°C to +60°C with full power available up to +50°C (derating linearly from 100% at +50°C to 60% at +60°C). Cooling air is drawn from the front of the unit and exits via the rear. The metal housing measures 12.48” x 6.69” x 2.5” (317.0 mm x 170.0 mm x 64.0 mm). All connections are rear-mounted. The operating altitude is up to 3100 m. MTBF is typically 90 khrs based on MIL-HDBK-217F, +25°C GB.
