Guest Posted October 7, 2021 Share Posted October 7, 2021 I want to power Kato Unitrack Turnout switch controllers but i have a dcc controller and NO Kato Power pack. How would i do this? NOTE: I am using HO Unitrack not N Scale Unitrack. Link to post Share on other sites More sharing options...
RMweb Premium Steven B Posted October 7, 2021 RMweb Premium Share Posted October 7, 2021 Are you using the Kato switches (blue with grey handle)? If so, then Kato 24-842 N Gauge - Unitrack AC - DC Power Converter (RRP £6) will let you power them from most power supplies. If you're not using the Kato switches the you need to provide a 12V DC supply, with the ability to change polarity. A DPDT switch should do the job, although I'd perhaps be a little cautious about applying the voltage all the time in case the motor coil can't cope with it. A non-latching DPDT switch should work in that case. Steven B. Link to post Share on other sites More sharing options...
Nigelcliffe Posted October 7, 2021 Share Posted October 7, 2021 As I understand the Kato official turnout switches, they are simply passing contact reversing switches. The input to those is 12v DC, the output is a brief amount of DC which reverses depending on direction switch is moving. The Kato AC-DC adaptor is only needed if the power supply is AC (ie. an old style transformer). If the power supply is DC (modern power-brick), then just need that, 12v. If using own switches, must use momentary action (non-latching) switches, such as push-buttons, or centre-biased toggle switches which return to centre. Or use an extra circuitry (simple electronics) to ensure the current only flows briefly. 1 Link to post Share on other sites More sharing options...
