SMRH manufactures transistorized hand-held controllers that outperform conventional resistive controllers in both output capability, smoothness and sensitive control for slow running such as shunting.Of late, its digital and computer controllers that lead the technology race for modelers, but personally speaking, I enjoy the safe running and reliability of DC control on the SMRH exhibition layout
The SMRH hand-held controllers can be utilized on any layout that is wired conventionally or wired for sectional power control (also referred to as cab control)Customers may utilize their existing controller as the power source for these controllers or see Power Packs to suit further down page.The controllers feature a three metre soft flex cable allowing the operator to move around the layout. They make the job of fixing derailments easier when the power control is in your hand
The 1.5 amp hand-held controller (Part Nos. DC15A - DC input or AC15A for AC input)
This model is suited to operators who require up to two locomotives running in tandem off the same controller.The components are all mounted in the hand-held itself and the matching panel socket is included.Power input may be any existing controller or power pack capable of either 12-15VDC or 15 -18VAC with at least 1.5 Amp output. The 1.5 Amp hand-helds are manufactured as either an AC or DC input.Both models feature an in built independant output for reverse loop wiring that allows continuous operation without stopping the train to change the polarity.
This model is designed for layout operators who need high current, for example, to operate multiple locomotives on the same train. This requirement is mostly seen in American modeling where running four to six locomotives is not uncommon. Exhibition and O gauge operators have also found the extra current capacity useful on large layouts and for prolonged running of long trains.The 4 Amp controller is supplied as a two piece unit comprising of a hand-held controller attached by a three-metre soft flex cable to a control box.The controller requires a 12-15 volt DC supply capable of producing at least 4amps. (There is no limit on the supply capacity current) It is recommended to feed this controller with a supply that exceeds 4amps to allow the maximum output through the controller for multiple loco operation.Track feeder wires around the layout should also be a reasonable core size to cope with the current supply
General notes:
All controllers have in-built electrical overload protection device that prevents the controller from ever being damaged by short circuits etc. As soon as the short is removed from the track the controller is ready to use. The controllers are built rugged for durability and is supplied fully assembled and tested. Warranty expressed as two years. (Items covered components, and labour)
