The 1693 & 1694 series high current switching power supplies from B&K Precision offer a powerful and efficient power supply in a compact and lightweight design. With an output of up to 900 W, these power supplies enable a variable output voltage and high output currents. The high efficiency of over 85% under optimum conditions ensures low energy losses and a reliable power supply.
Thanks to their compact design, high output power and precise control options, the 1693 and 1694 models are ideal for use in laboratories, electronics development and industrial applications. The devices have protection circuits against overtemperature and overvoltage as well as an analog remote control option for voltage regulation or for switching the output on/off.
The model 1694 presented here offers a variable output voltage of 1 V to 30 V with a maximum output current of 30 A. Compared to the 1693 variant, which offers a maximum current of 60 A at an output voltage of up to 15 V, the 1694 model is ideal for applications that require a higher output voltage with moderate current requirements.
Differences between the variants
- The 1693 model offers a higher current (up to 60 A) than the 1694 model (30 A).
- However, the model 1694 can provide a higher voltage (up to 30 V), while the model 1693 is limited to 15 V.
- The auxiliary output power of the model 1693 is 5 A, while the model 1694 only offers 3 A.
