Scientech - Model NUSI 500 Series -Single Power Supply

The SPS500 Single Power Supply is a linear solid state module that replaces the obsolete Foxboro 610A power supply. The SPS500 converts input ac power to a semi‐regulated output voltage for use as a current loop power source.   Standard SPS500 units have an internal   500 Ω pot to adjust total loop resistance.   All versions of the SPS500 are available   with an optional extended range internal resistance, using a 1,000 Ω pot in place of the 500 Ω pot.
