12 July 2021: Due to a flood at my home/shop, Harbach Electronics is closed until I get this mess cleaned up and all of the damage repaired. Effective immediately I will be closed how ever long it takes to clean up and repair the damage. All pending orders will be canceled and refunded via the method of payment. I am sorry for the closure but I have to get things repaired and cleaned up. I hope to be back open around mid-October 2021.
You can still view products, but no orders are being taken at this time. Sorry for the inconvenience!

SS-201-240 Soft-Start Module

$30.00

SKU: SS201-240 Category:

Description

The SS-201-240 limits inrush current during amplifier start-up by placing a small resistive load in series with the AC mains. The load is switched out of the circuit by the relays a few milliseconds later. The soft-start mounts inside the amplifier and safely limits inrush current to protect hard-to-find and costly-to-replace ON-OFF switches, tubes, filter capacitors and high voltage transformers.  The kit is for SB-200/201 amplifiers operating from 240 VAC mains and includes power resistors for 240VAC mains operation (20Ω 10 watt).
