Static electric fields generated solely by charges are insufficient to maintain a steady current. Therefore, a programmable DC power supply or a 27V DC power supply is utilized, leveraging the force of non-electrostatics to return the current from the negative electrode back to the positive electrode of potential. This maintains the potential difference between the two electrodes, thereby forming a steady current.
The reason programmable DC power supplies are called programmable is because they are set using digital inputs or encoders, rather than potentiometers to adjust voltage and current. Most programmable DC power supplies feature computer communication and programming capabilities. Important considerations for programmable DC power supplies:
(1) Special attention must be paid to the 27V DC power supply to ensure that there is no output short circuit.
(2) To output high currents, use low-loss conductors to ensure the parameters of the output load pass through.
Do not leave the equipment powered on when not in use for extended periods.
The programmable DC power supply features two programming methods: active and passive. The passive programming algorithm modifies the reactive resistance and input resistance to alter the output value. The active programming algorithm adjusts the output value of the reference voltage and the current. Additionally, there is also the programming speed of the power supply.
