Description

Jasper Electronics (JE) models TC2070-4A+PFC and TC2070-4N(A)PFC component 2070 power supply CalTrans modules are fully compliant to the State of California Department of Transportation (CalTrans) Transportation Electrical Equipment Specification (TEES) dated November 5, 2020 (designated Caltrans models 2070-4A and 2070-4N(A)) for use in Caltrans TEES 332L, 334L and 336L cabinets. Specific design requirements are detailed in the TEES document. The TC-2070-4 Series units are also fully compliant with NYSDOT (New York State Department of Transportation) requirements.

TC2070-4A, TC2070-4N(A), 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.

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 1 0-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 TC2070-4B and TC2070-4C as shown are user-requested optional configurations. The features and specifications listed may be revised as a result of ongoing development testing and/or additional user requested changes, but as of the user acceptance date of the first article production sample model (Revision Code A,) changes affecting the form, fit, function, or other features outlined herein shall not be permitted without prior notification to and written approval from the user. Please consult the factory for details.

AC Power Fail/ Power DownAC Fail and Power Down output lines go LOW (ground true) immediately upon power failure. The lines transition to HIGH within 50ms after both power restoration and supply are fully recovered. Lines driven separately

Linesync60Hz Square Wave Linesync signal is generated by a crystal oscillator which synchronizes to the 60Hz VAC incoming power line at 120 and 300 degrees. A continuous square wave signal is +5 VDC amplitude, and 50±1% duty cycle. The output has a drive sink capability of 16 mA. A 2K Ohm pull-up resistor is connected between the output and +5 VDC. The monitor circuit compensates for missing pulses and line noise during normal operation. Signal disabled when Sysreset transitions LOW and enables when Sysreset transitions HIGH
