In this post on Brass HO Trains we look at Power Supplies for Model Trains. There are various types of control system and power supplies for the model trains. Many of the manufacturers like Atlas, Bachmann, Kato USA Inc, Marklin, MRC are the leaders in the control systems. Most of the power packs are specific to the scales, but some may be used for more than a single scale model train. Control and power units for Brass HO trains are manufactured by companies like Model Power, Digitrax, MRC, etc.
The Model Power has two main models of the power packs for HO model trains. Electro is a fully filtered Micro controlled regulation pack. It has useful features like circuit breaker protection, Overload indicator light, Separate on/off switch, Super low speed performance and smoothness, no-screw terminals, Double insulated electric approved casing, etc. This model is powered to operate five trains at once and is compatible in AC and DC tracks. The second one is the Deluxe power pack that suits all trains and racer car sets. The unit is encased in a sturdy black plastic box and has forward and reverse switch and is UL approved. It also has a circuit breaker protection.
The Unitrack power pack from Kato USA Inc is used for the Kato Unitrack and locomotives. The unit can be used to control direction and speed, and has a circuit breaker with reset button and turnout control switch with swap-on socket. Products from MRC have features like pressure breaks, proportional tracking control, and monitoring of feedback from the layout to detect sudden changes in loads. One of the products, Control master, is a walkaround model that has hand held control with memory. The products give a 300 degree speed control for the Brass HO trains and other HO and N model trains.
Bachmann has come up with various control units for HO brass model trains. One such product is compatible with N, HO and On30 scales. This is used with DC operated trains and has features like plug-in wiring, power indicator light, direction control switch, and electronic circuit protection. The model has universal track power wire for other track systems with convinient E-Z-Track track power wire. The other model, E-Z Command Power Booster is intended for indoor use and can be used for Brass HO trains, N, O or even larger scale layout. The unit is designed to run many DCC locomotives and the output voltage can be altered to suit the scale for which it is used. There are a lot of safety features like thermal overload protection, and also includes air vents and a fan. The E-Z Command DCC Controller system is a digital system that controls speed, lighting and direction of multiple locomotive in N, HO and On30 scale from any manufacturer.
