产品特点 FEATURES

1 Isolated, regulated DC-DC converter with wide input range (200-420Vdc) and nominal 24V SELV output

2 High peak efficiency up to 94% and power density of 309W/in³

3 Adopts ZVS high-frequency switching topology for stable performance

4 Supports both remote sense and local sense operation to ensure voltage accuracy at load

5 Tight output voltage regulation over all line and load conditions

6 Equipped with comprehensive protections: overvoltage (OV), overcurrent (OC), undervoltage (UV), short circuit, and thermal protection

7 Offers full operational current limit to maintain safe operation within SOA

8 Compact VIA package available in chassis mount or through-hole types, with dimensions of 3.75×1.4×0.37 inches (95.13×35.5×9.4mm)

9 Provides up to 600W continuous output power and 25A continuous output current

10 Allows trim functionality to adjust output voltage when enabled

11 Supports enable/disable control via EN pin (requires VDDE preapplied before VIN)

使用场景 APPLICATIONS

1 Industrial automation systems: Power supply for control modules and sensors

2 Process control equipment: Provides stable 24V power to PLCs, transmitters, and actuators

3 Heavy machinery: Power distribution for on-board electronic components

4 Industrial power systems: Isolated power conversion for sensitive loads

5 Factory automation lines: Reliable DC power for motor drives and control circuits

注意事项 PRECAUTIONS

1 Input voltage slew rate: Ensure input voltage slew rate is less than 1V/µs; if exceeding, install a pre-charge circuit to protect input components

2 Input filter: Use Vicor's recommended input filter design (refer to official tool) to ensure system stability

3 External output capacitor: Must connect an external capacitor of 1000-10000µF with ESR ≤10mΩ for control loop compensation; for loads below 2% of rated current, use capacitors in the COUT-EXT-TRANSIENT range

4 Thermal management: Utilize conduction cooling from pin-side or non-pin-side of the VIA package; monitor internal temperature to not exceed the rated range (C-grade: -20~125°C, T-grade: -40~125°C, M-grade: -55~125°C)

5 Grounding requirement: Chassis of the VIA package must be connected to Protective Earth (PE) for Class I products; both housing surfaces need PE connection to meet safety and EMI standards

6 EN pin operation: EN pin is active only if VDDE is applied before VIN; otherwise, EN is ignored until VIN is removed and reapplied

7 Trim mode: Trim behavior is latched when VIN is applied (above VTRIM-DIS: non-trim mode; below VTRIM-EN: trim active) and remains until VIN is lost

8 Fault handling: Overvoltage protection (OVP) is latched; clear the fault by disabling EN pin or reducing input voltage below VIN-INIT

9 Input fuse: Install system-level input fuse according to current, voltage, ambient temperature, and breaking capacity requirements

10 Life support warning: This product is not authorized for use in critical life support devices/systems without Vicor's prior written approval
