KA22284 Power Indicator Module (3.5–12 V) Key benefits Quickly shows power presence and level: the integrated LED gives clear visual feedback so you can verify power status at a glance. Simple to configure: an adjustable power indicator lets you set thresholds or sensitivity without complex tools. Works with both AC and DC supplies: designed for flexible use across different power sources. Easy, reliable connections: convenient spring terminals simplify wiring and reduce installation time. Fits tight spaces: compact footprint of approximately 29 x 21 mm makes the module ideal where space is limited. What it does and why you need it Provides fast, unambiguous visual confirmation of whether a circuit is powered and roughly at what level, reducing troubleshooting time and preventing accidental power-on errors. The adjustable indicator adapts to different systems and tolerances so you can tune it for your specific application. Spring terminals avoid screws and improve contact reliability for frequent reconfiguration or testing setups. Important attributes Model: KA22284 Operating voltage: 3.5 V to 12 V Indicator: integrated LED for clear visual status Connectivity: spring-type terminals for quick, secure wiring Size: approximately 29 x 21 mm; lightweight and compact for tight installations Practical applications Prototype and test benches: use it to confirm power presence on development boards and wired prototypes without interrupting work. Small electronics and embedded systems: monitor supply rails on compact devices where panel space is limited. Field service and repair: portable enough to carry and use when diagnosing AC or DC power problems in equipment. Installation and use notes Install in close proximity to the monitored supply or circuit for best visibility. Adjust the indicator to the appropriate threshold for your supply range within 3.5–12 V. Use the spring terminals for quick connections; ensure proper polarity when used with DC sources. The KA22284 module delivers a compact, easy-to-install visual power indicator compatible with both AC and DC systems, suitable for a wide range of small-scale and portable applications.
