Description
The CalTrans TEES Model 206L Cabinet Power Supply is built to the specifications of the State of California Department of Transportation (CalTrans) Transportation Electrical Equipment Specification (TEES) November 05, 2020. No changes affecting form, fit, function or other features of the module outlined in this document are permitted without prior notification and written approval of CalTrans.
Jasper Electronics TEES Model 206L is a switching power supply capable of delivering up to 120 Watts of DC power through a single, regulated +24V DC output. It provides full output regulation across changes in AC Line voltage and output load over the full operating temperature range of -34°C to +74°C. Power Factor Correction is provided, reducing peak AC Line input current and the associated stress on wiring. This model has a functional AC input range of 80V AC to 270V AC input and 47 to 63Hz.
Model 206L is an open frame design, with the main PCB assembly installed in a grounded sheet metal chassis designed to be rack mounted in a TEES type PDA #2L, PDA #3L or PDA #4L assembly as commonly found in 332 or 336 style traffic signal control cabinets. This unit is directly interchangeable with earlier CalTrans Model 206 linear type power supplies, without requiring cabinet modifications.
