The BK Precision 1746 is a versatile DC power supply designed for a wide array of electronic testing and development applications. It provides a continuously variable output voltage from 0 to 16 VDC and a current output of up to 10 amps. The unit offers both constant voltage (CV) and constant current (CC) operation with an automatic and smooth crossover between modes, indicated by LED indicators. It features two selectable current ranges: a high range (0-10 A) and a low range (0-2 A) to enhance current settability and meter resolution for lower current values. The power supply is engineered for laboratory quality with excellent line and load regulation, and low ripple characteristics, ensuring stable and reliable power delivery for sensitive circuits and components.
### Technical Specifications
**Electrical Output:**
* **Output Voltage:** 0 to 16 VDC, continuously adjustable via coarse and fine controls.
* **Output Current:**
* High Range: 0 to 10 A
* Low Range: 0 to 2 A
* **Voltage Regulation:**
* Line (108-132 V): ≤(0.2% + 2 mV)
* Load (no load to full load): ≤(0.04% + 2 mV)
* **Current Regulation:** (Specifications for current regulation are not explicitly detailed in the provided documentation, but the unit offers constant current operation.)
* **Ripple Voltage:** Low ripple characteristics (specific RMS or peak-to-peak values not detailed in all sources, but consistently cited as a feature).
* **Constant Voltage (CV) Operation:** Regulates output voltage at the value set by the VOLTAGE controls. CV indicator (Green LED) illuminates when in this mode.
* **Constant Current (CC) Operation:** Regulates output current at the value set by the CURRENT controls. CC indicator (Red LED) illuminates when in this mode.
* **Crossover:** Smooth and automatic transition between CV and CC modes.
**Metering and Indicators:**
* **Output Meters:** Two large, easy-to-read analog meters continuously monitor output voltage and current.
* **Mode Indicators:** LED indicators (CV and CC) show the current operating mode.
* **Power Indicator:** LED acts as a pilot light.
**Protection and Reliability:**
* **Overload Protection:** Fully adjustable current limiting, settable from 5% to 100% of maximum output current, to protect both the circuit under test and the power supply.
* **Reverse Polarity Protection:** Prevents damage to the power supply from external reverse voltage.
* **Pre-Regulator:** Incorporated to limit internal dissipation and enhance reliability, especially at lower output voltages.
* **Isolated Output:** Either polarity (positive or negative) can be floated or grounded.
* **Continuous Duty:** Rated for continuous operation at full output current.
**Configuration and Expandability:**
* **Series Operation:** Two BK Precision 1746 units can be connected in series to create a power source with a voltage output of 0 to 32 VDC.
* **Parallel Operation:** Two BK Precision 1746 units can be connected in parallel (with appropriate balancing resistors) to provide up to twice the output current.
**Interfaces:**
* **Output Terminals:** Standard output terminals for connecting to the load. Polarity is clearly marked (+ and -).
* **Ground Terminal:** A ground terminal is provided for chassis and earth ground connection, ensuring safety and proper grounding.
**Physical:**
* **Dimensions:** Not explicitly stated in accessible documentation.
* **Weight:** Not explicitly stated in accessible documentation.
* **Styling:** Modern, functional styling with a logical and convenient control layout.
**Power Requirements:**
* **Input Voltage:** Designed for use with a polarized 3-wire AC outlet. Internal fuse for protection.
* **Line Voltage Conversion:** While not detailed for the 1746 specifically, other B&K Precision manuals mention international unit conversion capabilities for some models.
**Compatibility:**
* **Applications:** Suitable for a wide range of applications including electronics servicing, manufacturing, design labs, educational institutions, and hobbyist projects.
* **Accessories:** Available accessories may include hook-up cable sets (e.g., TL 5A).
