Programmable DC Power Supplies Model 9151 | Electrical measurement of BK Precision
The 9151 series are high performance linear-regulated programmable DC power supplies that provides excellent performance and features not found in other supplies in this price category. These supplies are designed for applications in design verification, production or university labs that require high yet clean and reliable power, combined with excellent resolution, accuracy and fast transient response time.
- Very low ripple and noise due to linear regulation
- Excellent display resolution
- Fast transient response time (<120 µs)
- SCPI compatible
- Communicate via USB Interface, using included USB to TTL serial converter cable
- List mode operation for increased throughput
- Very quiet due to intelligent fan speed control
- For bench use or rack mountable
- Application Software for front panel emulation and simple test sequence generation included
- Digital port with Remote Inhibit (RI) useful for turning multiple power supplies On/Off simultaneously
- Over voltage protection
- Digital Volt Meter and Milliohm Meter
