DP101-TX90
  1.  Industrial 90W PoE Giga Injector

The DP101-TX90 is a high-performance industrial 90W PoE injector designed for robust power delivery in demanding environments. It supports IEEE 802.3af/at/bt standards and features an intelligent smart-PoE detection algorithm that ensures compatibility with both standard and legacy/non-standard PD devices. The injector can automatically deliver power over 2-pair or 4-pair wiring and safely limit output when connected to non-standard PDs, such as outdoor dome IP cameras or other high-power equipment. Engineered for reliability, the DP101-TX90 operates flawlessly in extreme temperatures from –40 to 75°C, features IP40-rated metal housing, and meets stringent industrial EMC standards—making it ideal for harsh industrial applications.

PoE Operation mode

PoE Power Output Enable/Disable

Auto Mode: In Auto Mode, the PSE follows the complete PoE sequence, including Detection, Classification, Powering, and Disconnection. This mode is enabled when DIP switches 2–6 are set to the “On” position.

Manual Mode: In Manual Mode, the Power Sourcing Equipment (PSE) delivers power directly without executing the standard PoE procedures. Detection, Classification, Powering, and Disconnection behaviors are bypassed. The power budget is controlled according to the PoE Class (0–8) configured via the DIP-switch settings.
PoE power budget

IEEE802.3af:15W @ typical DC 48V, Rating 46~57V

IEEE802.3at:30W @ typical DC 52V, Rating 50~57V

IEEE802.3bt:90W @ typical DC 55V, Rating 53~57V
PoE Protection

The DP101-TX is equipped with multiple protection mechanisms, including Over-Voltage Protection (OVP), Over-Current Protection (OCP), and Over-Temperature Protection (OTP). When any of these events is detected, the system immediately shuts down the PSE power output and will not resume operation until the fault condition has cleared.

Over-Temperature Protection (OTP) Threshold:

Shutdown Temperature: PSE output is disabled when the internal temperature exceeds 150°C.

Recovery Temperature: PSE power output automatically resumes once the temperature drops below 129°C.
