NK’s AC and DC input current switches available through Mod-Tronic

Current switches by NK Technologies

Mod-Tronic Instruments Ltd. carries a broad range of measurement solutions, including current-sensing products by NK Technologies. For more than 30 years, this manufacturer has made more than 1,300 models of devices, ranging from current transducers to signal converters, with an unmatched variety of styles and variations to comply with any industrial and automation requirements. This wide portfolio includes two types of input current switches, AC and DC models; as all NK products are, these devices are stocked for quick delivery around the world.

Fixed or adjustable set points

These devices are ideal for on/off status, monitoring AC or DC current loads to detect overload or underload condition. Every unit blends a CT, a signal conditioner, and output contacts into one single device. Both the AC and DC models provide input ranges from one to 1,600 Amps, plus fixed or adjustable set points with indication. These input current switches are available in solid-core models with front or top terminals, plus split-core versions for easier installation. The switches have normally open or normally closed output contacts for switching AC or DC, and they comply with the RoHS2 standard with a five-year warranty.

The AC current input switches have Solid State contact or SPDT relay outputs. They are also self-powered, with low-voltage AC/DC and 120VAC power options. The following models in this category are available from Mod-Tronic:

• Current switches with transmitter output – including the ATS1, ATS2, and ATS-420-SDT series
• Fixed-set-point models – two versions, the AS1 compact case and AS1 NOR-FT-GO
• Jumper selectable range models – the AS3 and ASX series, each of which has two models
• Large-aperture and high-current models – two designs, each with four series
• Low-current models – the AS0 series, with a sensing aperture diameter of ¾ of an inch
• Low-voltage AC/DC power options – 15 series available in this category, with different features and sizes
• Wide-current-range models – six designs available in three series: the ASC, AS1, and ASM series

NK’s DC current input switches have low-voltage AC/DC power options. Two models are available – the DS1 series, with fixed set points, and the DS3 series, with adjustable set points.
