Power Supply FAQ's

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 C.C. Steven Customer Service Representative if you need  additional assistance.

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.

How Many Outputs Do SIMCO 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.

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.

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 C.C. Steven Customer Service, or email us if you need shielded cable. You can contact Customer Service at (805)  658-0207.

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.
