- 1)What Do SIMCO Power Supply Model Numbers Signify?
- The model number of a SIMCO power supply will tell you the required input and resulting output. The first numeric character indicates input voltage, the second numeral is Hz, and the third is output voltage.
For example, an F167 Power Supply is 120 VAC input, 60Hz (some models are both 50Hz and 60Hz), and 7,000 volts output. A D257Q is 230 VAC input, 50Hz, and 7,000 volts output.
- 2)How do Power Supplies Work?
- SIMCO power supplies are designed to be connected to a SIMCO static neutralizer to operate according to design specifications and to remain under warranty. Power supplies are offered in a variety of input and output voltages and mechanical configurations. Most SIMCO power supplies are UL listed (USA), CUL or CSA certified (Canada) and CE compliant (Europe).
Standard line voltage (120 VAC, 60 Hz or 230 VAC, 50 Hz) is converted to an output of 4,000, 6,000 or 7,000 volts AC to enable the static control equipment to ionize air using high voltage discharge. In some cases, the power supply is directly integrated into the product. In the event of a direct short circuit to ground, the output current is limited to a maximum of 3mA.
Considerations for power supply selection include application and location, bar length, cable shielding and length, and number of connections. Recommended power supplies are listed with each product on this website. Contact your SIMCO representative or Customer Service Representative if you need additional assistance.

- 3)How Many Outputs Do SIMO Power Supplies Have?
- Most power supplies come with two or four outputs, which accept standard SIMCO SLCC screw in connectors. This means they can accept two to four static eliminators, up to the maximum length of static bars which the power supply will power.
Power supply models that start with the letter "N" and "M" have an internal terminal block which requires that the static eliminator's cable be striped and attached directly to the terminal block, rather than being attached with an SLCC connector.
- 4)What Is The Total Maximum Length Of Static Bar(s) That Can Be Attached To One Power Supply?
- All power supplies have a limitation on how many static eliminators they can power. This limitation is expressed as the maximum number of inches of static bar which a power supply can power. The calculation of number of inches is based on the effective length of the static bars. For example, two twelve foot effective length bars (288 total inches) could be powered by an N167 Power Supply (300" maximum), but both bars could not be powered simultaneously by an F167 Power Supply (200" maximum). You would need two F167's, one for each twelve foot static bar.
If a static bar is equipped with corona free shielded cable (a braided, silver colored cable) the length of the cable must be added to the length of the static bar. This is because the shielding creates a load on the power supply in the same way the static bar does.
- 5)What Is Shielded Cable?
- Shielded cable is distinguished by a silver colored, braided metal exterior cover. Shielded cable reduces the amount of electromagnetic interference (EMI) and radio frequency interference (RFI) emitted from the cable. The operation of some sensitive electrical components is adversely affected by EMI and RFI. Contact your SIMCO Representative, Customer Service, or email us if you need shielded cable. You can contact Customer Service at (215) 822-6401.
- 6)Can Static Eliminators Be Used In Hazardous Locations?
- Some manufacturing locations are designated hazardous locations due to the nature of the manufacturing process or chemicals and materials being used in the area. SIMCO offers the XP-2 static bar, XP167 and XP267 Power Supplies, and XP-20F blower specifically for operation in areas classified as Class1, Division 1 and 2, Group D hazardous locations.
