Anaheim, CA — (ReleaseWire) — 03/02/2023 — Jasper Electronics TC2070-4 models are chassis mounted, fully enclosed, 4-output (with standby) switching power supplies capable delivering up to 74 Watts DC. They are designed for non-redundant “cold pluggable” installation in the end product. AC input and PE are via a non-detachable power cord at the rear. DC output power, signal, and control connections are through 10-circuit and 12-circuit connectors on the front of the supply. Adjacent on the front panel is a line-side operator accessible input fuse, an On/Off switch, and output condition indicator LEDs. These units are convection cooled, with an extended operating temperature range. They are directly interchangeable with all other CalTrans approved 2070-4 type modules with identical AC input ratings. Models TC2070-4A, TC2070-4N, TC2070-4B, TC2070-4C component non-power factor corrected power supply modules are fully compliant to Cal Trans TEES July 2009 (including Eratta No. 1 January 2010 and Errata No. 2 July 2014.)
