DARE Electronics, Inc.

DARE Electronics solid state relays incorporate advanced microelectronic hybrid technology and are available from low level to 50 amps. Solid state relays have distinct advantages over electro-mechanical devices including: no contact bounce, arcing or flashing; immunity to contact contamination and oxide formation in dry or normally open circuits; and immunity to shock and vibration thus preventing unwanted contact closures. Furthermore, DARE's solid state relays yield much longer switching life, higher reliability, and reduced electromagnetic radiated and conducted emissions. Features include:Optical or transformer input to output isolationZero voltage turn-on; zero current turn-offLogic compatible input current levels3 phase load switching capabilitiesHybrid microelectronic designHigh transient immunityFast switching speedSnap action switching General SpecificationsWhile DAREs solid-state relays are available in a wide variety of custom configurations, these general specifications represent some of DARE's current product capabilities: Solid-State RelaysInput VoltagesFrom 3 to 200 VDC or 3 to 440 VAC Temperature Limits-55C to 110C (Optical)-55C to 125C (Transformer) Load VoltagesUp to 500 Volts AC or DC Input to Output IsolationUp to 4000 VRMS Load CurrentsFrom low level to 50 amperes Available Outputs(AC) Triac or inverse-parallel SCR's, 1 or 3 phase(DC) SCR, MOSFET, Darlington or bipolar transistor

DARE Electronics designs and manufactures flashers to MIL-F-26301 and other flashers with solid-state or electro-mechanical outputs. Used on military, airborne, or ground support applications, DARE flashers and recycle timers can periodically turn on and off navigation, position, warning or indicating light or sense and indicate a malfunction in certain systems and activate an alarm. FA-18 Aircraft Navigation Light FlasherHermetically sealed and encapsulated for immunity to shock, vibration and environmental extremes, DARE flashers are designed and constructed to insure conformity with applicable military specifications, including:Temperature, vibration, shock, acceleration, and altitude per MIL-STD-810Voltage Transients per MIL-STD-704, andEMI per MIL-STD-461 Design features and option include:28 VDC or 115 VAC 50 Hz, 60 Hz, or 400 Hz operationSingle or multiple independent output channelsSolid state or SPDT, DPDT, 3PDT, or 4PDT electromechanical outputs Available in a wide variety of finishes, enclosures, connectors, and mounting arrangement, DARE flashers and recycle timers can be powered from sensing input lines or from separate AC or DC supply and supplied in inductive & lamp load models. In addition, DARE can supply flashers and recycle timers that can be used as direct replacements for thermal or motor driven timers.
