Description
The CalTrans TEES Model 206E 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.
The TEES Model 206E is a switching power supply capable of delivering up to 240 Watts of DC power through a single, regulated +24V DC output. The unit is an open frame design, with a main PCB assembly installed in a grounded sheet metal chassis designed to be rack mounted in a TEES type PDA #2LX or PDA #3LX assemblies commonly found in 332LS, 336LS, 342LX, 344LS and 346LX style traffic signal control cabinets.
The TEES Model 206E 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. The TEES Model 206E functional AC input range is 80V AC to 150V AC input and 47 to 63Hz.
Please refer to the product Operating Manual for more information.
| INPUT | |
| Voltage/ Current Rating | AC 90-135V, 57-63Hz, 3.3A max, 1Ø |
| Input Fuse | AC 5.0A, 250V delayed (slow-blow) action 5x20mm AG cartridge type external line fuse provided, operator accessible. Fuse IEC 60127-2/3 compliant (TEES 3.4.2.3) |

| Inrush Current | Soft start (~25ºC cold start) 30Apk @ AC 115V |
| Efficiency | At AC 115V: >82% @ 100% load |
| Under Voltage Protection | Auto output shutdown when AC input falls below safe operating limits. Automatic recovery when input rises to within normal operating range |
| OUTPUT | |
| Voltage/Current (V/A) | V1 |
