The 1696B series from B&K Precision includes compact, programmable 200W DC power supplies that offer a variety of control and protection features. They are equipped with features normally found in more powerful and expensive devices. These include list mode programming for repeatable sequences and 10 user-defined voltage and current presets for a quick return to specific settings.
These power supplies are ideal for numerous applications in research and development (R&D), production and quality testing, product evaluation and teaching and training in technical laboratories.
Features of the series:
- Built-in voltage, current and power meter
- List mode with up to 20 programmable steps
- Automatic switching between constant voltage (CV) and constant current (CC)
- Protective functions: Over voltage protection (OVP), over current protection (OCP), over temperature protection (OTP) and key lock
- Control of up to 31 power supplies via an RS485 interface
- Storage of up to 10 voltage and current values for quick recall
- Lightweight and compact for versatile use
- Large, backlit LCD display
- Variable speed thermostatically controlled fan for low noise
- USB and RS485 interfaces with support for basic SCPI commands
The 1697B power supply presented here is a variant of the series that offers extended voltage regulation from 1 to 40 V at a maximum current of 5 A. Compared to the other models in the series, the specifications differ as follows:
- 1696B: 1-20 V / 0-10 A
- 1697B: 1-40 V / 0-5 A
- 1698B: 1-60 V / 0-3.3 A
All models have a maximum output of 200 W, but different voltage and current ranges for different applications.
