SP16A power backup

Doehler & Haass SP16A – Powerpack for Reliable Operation

The Doehler & Haass SP16A is an ultra-compact powerpack designed to keep the decoder powered through brief voltage interruptions caused by dirty wheels, switches or track gaps. With dimensions of only 13 × 9 × 2.6 mm, it fits into most locomotive types, even smaller H0 models.
Its integrated inductance makes the SP16A fully compatible with asymmetric braking sections. It offers 470 µF capacity at 16 V and supports operating voltages up to 30 V.
