About Power Conditioning EquipmentSurge Protectors and Power ConditionersMost people are familiar with surge protectors, which guard against damage due to suddenspikes in the electrical current. A power conditioner provides protection against surges inpower just as a surge suppressor does, but a power conditioner also maintains a continuousvoltage during temporary voltage reductions, such as a brownout. This is referred to asconditioning. Power conditioners also can filter EMI emanating from a power source and cansmooth the rhythmic cycle of alternating current. While surge protectors safeguard equipment,a power conditioner cleans the signal, eliminating interference on the line.CRS recommends the PowerVAR ABC065-11 (CRS P/N 701002), a 0.65 amppower conditioner that is suitable for most ECR applications. POWERVARstandard power conditioners are for use with any microprocessor based electronicequipment. Thanks to their low impedance isolation transformer, you can trustthese conditioners to protect your sensitive equipment from the biggest problems for today'scomputers.Ground Guard ConditionersPOS systems consisting of workstations connected in an Ethernet network must have thesame point of reference, (i.e. common ground potential for all equipment in the system.)Unlike electronic loads, traditional electrical loads such as motors, lights, heavy appliances,etc. use the equipment ground for safety purposes only and do not rely on it for properoperation. Computer equipment, on the other hand, introduces the equipment-groundingconductor as an active part of the power supply in referencing digital logic. Thereforenetworked POS systems require isolated/dedicated ground circuits to insure proper operation.CRS recommends POWERVAR ground guard conditioners for networkapplications. Only the “Ground Guard” conditioner from POWERVAR can beused as an alternative to isolated/dedicated ground circuits. Traditional powerconditioners cannot be used as an alternative as they do not address the groundissues over a network. The Ground Guard conditioner must protect every piece of equipmentin the POS system in order to operate properly. POWERVAR Ground Guard powerconditioners are available in sizes from 0.65 to 16 amps, to protect single or multiple POScomponents.SAM4s SPS-2000 Operator Manual v1.13 Introduction • 9
