I have a 100W 50 ohms signal generator amplifier with a 35 meters coil wire (1.5 mm) as a load, BNC connectors. The requirement is that only the BNC POSITIVE pole is connected to the wire and used as antenna. The amplifier require a minimum of 4 ohms load. This is not a closed circuit antenna...
Good morning all.
Before I start I am not an electrician and am relatively new to this topic.
Current set up Axpert 5.5 Kw inverter, 7 x 420 watt panels in series and 2 x US 5000 Pylontech batteries paired (1 master 1 slave). System working fine will no issues.
I know this may have a simple...
I live in Thailand and my home has 240v, 3 phase power supply. I want to add an electric car charger but first want to determine what the outlet in the garage can handle so I can size the charger appropriately. The circuit breaker this outlet connects to is 16A. Does this mean the outlet is...
Hello
Is it possible for solar panel monitoring to over state the actual power generated by the system? My friend’s 6.4kW system has generated 1280 kWh in the 82 days since its commissioning on 1/12/2022. Extrapolation of this output predicts an annual production of around 5,700 kWh which...
Hi Forum people. First time post here.
I have a pair of semi flush fittings that are currently 10 Halogen capsules per fitting. I want to convert these to LED at 2 watts per capsule. Space is a very limiting factor. Each fitting currently has a round transformer inside. I only have an 80mm...
Just an idle thought - has anyone any experience of using the DC output of solar panels to directly feed an immersion heater, to avoid the expense and losses associated with an inverter? Evidently, a changeover relay would be required to utilise the usual 240V AC supply at times of low or zero...
Hi every one. I have a NC relay with the below features which is written on the relay:
Input voltage:12V dc
Output switching voltage: 220V ac
Output switching current: 5 amp
Can I use this relay for a 400V ac, 0.1 amp Output case?
Can the relay stand up to this high voltage?
Thanks
I designed basic clipper circuit using single 3.3v Zener.When i simulate this on proteus and while checking output by keeping knob on AC of respective chanel and output shown is 2v positive and 2v negative from refrence ground(obviously wrong).When i change knob to DC it shows correct output of...
Hi,
I have one of these power supplies.....

The PSU has a USB connection, and the light can "mate" with...
Hello guys, I am using Shinko BCS2R00-00 temperature controller for a packing machine. The indicator shows that the output is on but there is no voltage output from the controller output terminal. So, the mould was not heat up. I have change to a new temperature controller, but still have the...
Custom hot tub with a spa pack controller. Everything is 3 wire (red, black, white) 220V. Everything is grounded with lugs.
Goal: I have two jet pumps and one air blower controlled by the spa pack. I would like to use a relay system to prevent the air blower from turning on unless one or...
hi,
I want to install leds that turn on from door open which is a negative switched signal ive already checked
and to stay on after car is switched on.
so basically if door is open/ ON
if engine on/ ON
if door open and engine on then/ ON
doors closed engine off/ OFF
by engine on i mean as soon...
HI all,
have a couple of LED tape to put onto two Lanterns in a flat roof, can i put the drivers in a cupboard and run RGBW cable (that looks like speaker wire ) on the output and run them 8 mtrs for one lantern and 10mtrs to the other. will there be a problem with volt drop or the output...
Hi!
I want to solder a TRS cable to a circuit amplifyer.
The amplifyer has +, - and OUT as outputs. I have heard that it should be possible to use a 3.5 mm TRS cable but I'm wondering to what output I should solder the wires from the TRS cable.
Someone told me that I should use either TIP or...
I have a workshop in a remote location which I rent out. The incoming supply is 3 x 16A three phase on 180m of 16mm SWA.
An upcoming customer has a machine which needs a 32A single phase supply. (Actual load about 25A.)
The energy is there, but it's split across the three phases. Is there some...
Hi all, need to replace a failed 500w halogen PIR floodlight. This one was a dual output model that had an adjustable dimmer on the PIR housing for setting night time dusk to dawn illumination but switched to full brightness when it detected motion.
Has anybody come across an LED floodlight with...
Just installed an UPS and I have a multi-meter that I use to check if a wall outlet is grounded
Just tried it on one of the UPS outlets (2 prong) by placing the multi-meter red probe to the metal and the black one to the right side of the outlet and it reads 0
Is this normal? Same measurement...
