3 Output characteristics: Nominal output voltage of 24V, rated output power of 250W; programmable output voltage range of 10-110% of nominal value (note: trimming below 90% may require a minimum 10% load)

4 Regulation performance: ±0.4% regulation from no load to full load; line regulation ±0.2% (low to high line at full load); temperature regulation ±0.005%/°C over the operating temperature range

5 Efficiency: Up to 87.5% (typical at nominal input, 75% load, 25°C)

6 Thermal performance: T-grade temperature range—operating temperature of -40 to +100°C, storage temperature of -40 to +125°C; thermal resistance (baseplate to sink with thermal pad) of 0.14°C/Watt

7 Isolation: IN to OUT isolation voltage of 3000VRMS, IN to baseplate of 1500VRMS, OUT to baseplate of 500VRMS

8 Key functional features: Isolated output, parallelable with N+M fault tolerance (supports current sharing), low-noise ZCS/ZVS switching architecture, compact size (2.28x2.2x0.5 inches/57.9x55.9x12.7mm), high power density (up to 100W per cubic inch)

9 Pin style: Long ModuMate (N in model) with gold finish; baseplate: slotted (blank in model)

使用场景 APPLICATIONS

1 Industrial and process control systems: Provides stable DC power for sensors, actuators, and control units in harsh industrial environments

2 Distributed power systems: Used in telecom infrastructure (e.g., base stations) to convert high-voltage DC to 24V for various components

3 Automatic Test Equipment (ATE): Delivers precise and reliable power to test instruments and Devices Under Test (DUTs)

4 Off-line systems: Compatible with auto-ranging or Power Factor Correction (PFC) front ends for AC-DC conversion applications

5 Medical equipment: Suitable for non-life-support medical devices (note: life-support use requires Vicor's prior written approval)

6 Communication systems: Supports power needs for routers, switches, and other network devices in data centers or field deployments

注意事项 PRECAUTIONS

1 Electrical safety: Do not exceed the maximum rated output current (10.42A for 24V/250W); avoid overloading to prevent module damage

2 Dynamic loading: Applications with dynamic load changes exceeding 25% of rated current must be reviewed by Vicor Applications Engineering

3 Output voltage trimming: Trim down—available output power decreases proportionally with voltage reduction; trim up—reduce maximum output current by the same percentage as voltage increase; do not trim above +10% of nominal voltage to avoid triggering over-voltage protection (OVP)

4 Parallel operation: Follow Vicor's design guidelines (AC-coupled interface for up to 3 modules, transformer-coupled for 4+ modules; use modules of the same input/output/power level)

5 Thermal management: Ensure proper heat dissipation (use thermal pads or greased surfaces) to maintain baseplate temperature within the operating range (-40 to +100°C)

6 Storage and handling: Store in ESD-safe packaging; keep in a temperature-controlled environment (15-38°C) with non-condensing humidity

7 Soldering and mounting: Follow Vicor's design guide for soldering (wave solder <5sec at 260°C, hand solder <7sec at 390°C); apply a mounting torque of 5 in.lbs (0.57N.m) for baseplate screws

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