BESTACT IMPROVES RELIABILITY FOR VARIOUS SYSTEMS AND EQUIPMENTS. FEATURES OF THE BESTACT SERIES OF PRODUCTS Bestact = Conventional Reed Switches + Mechanical Power Relays Bestact can perform the jobs of both conventional reed switches and power relays. Because a single Bestact replaces both, circuitry is simplified and entire circuit reliability rises significantly. A substantial cost savings can be achieved in that no contact protection snubbers/diodes is needed, minimal connections and reduced wiring circuitry are needed in the actual circuit design. Bestact can switch both AC and DC...

ELECTRICAL LIFE Electrical life tabulated below is B10 value in a single test (at the condition shown in IEC PAS 62246-2-1) at Yaskawa. It is not a value in a multiple environment such as temperature and vibration. It is necessary to test actual products before initial operation. The circuit that drives coils adopts a direct making method which applies rated coil voltage (instant ON and instant OFF). In the circuit where the voltage applied to coils gradually increases or decreases, electrical life might decrease. 1. ELECTRICAL LIFE WHEN APPLYING TYPICAL LOADS 1. For inductive load, L/R = 1...
