Means of output voltage regulation in Power Taps

[Lewis Hoff]

Do your power taps like the PHTCELTAP have an inbuilt transformer to regulate the output to my desired 120VAC? Will it accept 277VAC and give out 120VAC?

The PHTCELTAP from RFWEL Engineering does not step down voltage. It will pass through whatever voltage it receives from the luminaire. We however do have products that will accept your 277VAC and give a regulated AC output of 120V. Others like the FP289A-120-CNB-A and FP289A-120-CNB will take 240VAC and give 120VAC.

Wait, so this is a step-down converter (step-down transformer)? I have a 240 VAC that power tap will give me a regulated 120 VAC? i thought this just passed through whatever voltage it got from lamp post? Also, another question, do you have something that can input 120 VAC and output 24 VDC - this way we can feed it directly to our wireless access point without having to go through the AP's power brick? How much current does it provide (the specs for the AP show that typically power is 56 Watts).

The PHTCELTAP from RFWEL Engineering does not step down voltage. To step down from 240V to 120V you would need either FP289A-120-CNB-A or FP289A-120-CNB with one allowing for dimming control passthrough and the other having no such functionality.

To get 24VDC from 120VDC the following variants will suffice. For those listed here the output is delivered via an RJ45 interface. They are rated for 24VDC at 1A.

An important note is that streetlight photocell power taps come with various voltage outputs. The output can be AC/ DC/ PoE and can be stepped up/ down as required. It can even be delivered using diverse terminations like bare-wire pigtails, RJ-45, micro/ mini – link or a NEMA/ IEC receptacle.
