As I basically need something to mimic a 200-250W power tool. But a simple resistor is not a very good simulation for another reason: It is a pure ohmic load. You want to lose some of the power to something else than to the object?? Small size 4x4", rugged , as lightweight as possible and the least emitted heat . Per avere un tasso di cambio aggiornato, utilizza il. That may or may not be important for your tests. It is not working reliablly, turns on, but then goes off right away, will not dim most of the time, when it does it "stutters" and goes off. But you can use 4 (2 parallel strands of 2 serial ones). Lamps are fragile and emit a lot of heat. GEE.... P=U*I... P would be Power=Watt; U would be Volt (voltage); I= would be current (AMPS). I have tested my requirements and what I get is ........ 110V 60W bulb is not enough while a 110V 500W halogen is sufficient for my application. But more importantly is making sure you are using an exact 50 ohm test variable that won't change like an antenna system might. Them people here are kind of my "soul-mates". You'll probably have to mount them on a heat sink and cool that by a fan. It’s used to allow full power output while testing or experimenting without radiating a radio frequency signal. The inductive load is 1/3 of the resistive load. 50 Ω DUMMY LOAD . What are my options. Series: RF Dummy Load. Yes, But you need thermal paste and a heatsink. Max power: 4000W. But again lamps are fragile and they emit way too much heat for my application anyway. How inexpensive, depends on the dissipation you need (QRP (5-10 W) or (much) more) and how long you want to be able to apply power without frying the dummy load and setting your shack on fire. Those draw more current as they do more work. INSTRUCTABLES, (to write that, for a FIN is a bit of challence), is for time to be one of my ABSOLUTE favor's to follow.
