Description
SM7860 Power Source Unit for MLCC Leakage Testing
The SM7860 Power Source Unit is purpose built to meet the demanding requirements of MLCC leakage current measurement systems. Designed to integrate directly with the Hioki SM7810 Super Megohm Meter, this power source delivers precise, stable voltage across multiple channels, making it an essential component for high throughput capacitor testing environments.
Multi Channel Test Systems
One of the key strengths of the SM7860 Power Source Unit is its ability to support complex multi channel configurations. The unit allows dual line output voltage settings across 8 or 16 channels, with system expansion supporting up to 32 channels in total. This flexibility enables engineers to scale their MLCC test setups efficiently without sacrificing measurement accuracy.
Precise Voltage Control
The SM7860 provides output voltages up to 1000 V, making it suitable for a wide range of MLCC testing conditions. Each channel supports individual output control and current limiting, allowing operators to fine tune test parameters for different capacitor types. With an output voltage accuracy of ±2 percent of the set value and minimal inter channel error, the system ensures consistent and repeatable measurement results.
Safety and Reliability
Safety and reliability are central to the SM7860 design. The unit supports discharge of charged capacitors, reducing risk during test transitions. High current output capability of up to 50 mA per channel helps reduce the need for frequent backup charging, improving test efficiency. For high voltage operation at 1000 V, output current is safely limited to 10 mA per channel.
Connectivity and Integration
The SM7860 Power Source Unit offers multiple interface options including GP IB, RS 232C, and external I O, making it easy to integrate into automated test systems. Available in both 100 V AC and 220 V AC power supply variants, the unit is produced to order to meet specific regional requirements. Its robust construction and stable performance make it ideal for long term use in production lines, research labs, and quality assurance facilities.
