The ALT alternating relays are used to alternate between two loads. The ALT is commonly used in duplex pumping applications to balance the runtime of both pumps. The ALT-S is used in single high-level float applications. When the float switch opens, the alternating relay changes state, forcing the other pump to run the next time the float closes. All ALT relays have a built-in debounce feature that prevents the relay from changing state if the switch or float contact bounces momentarily. The ALT-X has an internal cross-connected relay and is used in dual high-level float applications. These floats are commonly referred to as lead and lag floats. The pumps alternate as in the ALT-S version but the crossconnected relay configuration allows both pumps to run simultaneously when both the lead and lag floats are closed. These relays are also available with a built-in switch (SW option) that is used to manually force one of the pumps to run every time the float switch is closed. This is helpful when a pump has been removed for repair or for test purposes. In the case of the ALT-X-SW, the switch essentially forces one pump to be the lead pump, while still allowing the second to run when both floats are closed. Must use the OT08PC socket for UL Rating!

The AQ0502-02RTG provides low capacitance, 2 channel unidirectional and a high level of protection for electronic equipment that may experience destructive electrostatic discharges (ESD). The typical capacitance of 1.0pF helps ensure excellent signal integrity on the most challenging consumer electronics interfaces, such as USB2.0, 10/100/1000 ethernet, display port.It can safely absorb repetitive ESD strikes at ±22 kV (contact discharge, IEC 61000-4-2) without performance degradation and safely dissipate 2.5 A of 8/20 μs surge current (IEC 61000-4-5 2nd edition).

The AQ0502-02STG provides low capacitance, 2 channel unidirectional and a high level of protection for electronic equipment that may experience destructive electrostatic discharges (ESD).

The bidirectional AQxxC-01FTG series is designed to replace multilayer varistors (MLVs) in electronic equipment for low speed and DC applications. It will protect any sensitive equipment from damage due to electrostatic discharge (ESD) and other transient events. The AQxxC-01FTG series can safely absorb repetitive ESD strikes of ±30 kV (contact and air discharge as defined in IEC 61000-4-2) without any performance degradation. Additionally, the AQ05C can safely conduct a 30A 8/20 surge event as defined in IEC 61000-4-5 2nd Edition.

The AQ1005 TVS includes back-to-back breakdown diodes fabricated in a proprietary silicon avalanche technology to provide protection for electronic equipment that may experience destructive electrostatic discharges (ESD). These robust diodes can safely absorb repetitive ESD strikes above the maximum level specified in IEC 61000-4-2 international standard (Level 4, ±8 kV contact discharge and ±15 kV air discharge) without performance degradation. The back-to-back configuration provides symmetrical ESD protection for data lines.

The AQ1205-01FTG bidirectional TVS is fabricated in a proprietary silicon avalanche technology. These diodes provide a high ESD (electrostatic discharge) protection level for electronic equipment. The AQ1205-01FTG TVS can safely absorb repetitive ESD strikesof ±30 kV (contact and air discharge as defined in IEC 61000-4-2) without any performance degradation. In addition, it can safely dissipate a 7A 8/20μs surge event as defined in IEC 61000-4-5, 2nd Edition.
