DOC WATTSON ANALIZZATORE DI ENERGIA

Price: 110,00€

Ask a question about this product

Questo strumento, posto in serie a un carico, non vi indicherà banalmente tensione e corrente assorbita, ma il consumo in A/h e W/h.

Questi parametri sono una indicazione molto più sensibile del consumo effettivo del vostro carico rispetto alla banale misura con un amperometro.

I Watt/ora in particolar modo tengono conto anche delle vaiazioni di tensione ( ad es. una batteria che si sta scaricando)

E' uno strumento utilissimo per fare il " fine tuning" dei consumi di un apparato, cosa molto importante nel QRP come nel modellismo e perchè no, su Apollo 13

Description

An RV or marine battery monitor should at least tell you the Amp hours drawn from your battery and the Amps being drawn. Our "Doc Wattson" battery monitor does that and much more.

The Amp hour (Ah) and Kilo Watt hour (KWh) measurements are much more accurate "fuel gages" than voltage measurements which depend on many other factors. Kilo Watt Hours are better than Amp hours because the effects of voltage change are included in calculating the actual energy delivered to the load. Ah and KWh are much more accurate than the voltage based RV or marine "Battery Indicator" measurements.

Peak Amps and minimum volts measurements show you even short duration load events and help you troubleshoot hard to find electrical problems. Statistics are reset when power is removed.

Doc Wattson helps you evaluate the effect of component changes and of system tuning on performance.

Product Comparison

Doc Wattson Meter
Parameter	Range	Resolution	Accuracy (worst-case)
Voltage	0-60 Volts *	0.01 V	± (1% + 0.035)
Current	0-100 Amps ***	0.01 A	± (2% + 0.06)
Power	0-6554 Watts	0.1 W
Charge	0-6554 Amp hours	0.1 Ah
Energy	0-650 Kilo Watthours	0.01 KWh (10 Wh)

Increased measurement range compared to Watt's Up Meter shown in bold type.

But only measures seven DC values with less resolution:

Amp-Hours: (0 - 6554)
Kilo Watt-hours: (0 - 650)
Amps: (0-100 peak)
Watts: (0 - 6554)
Peak Amps & minimum Voltage ("sags")

Works with 12, 24, 36 or 48 volt batteries up to 60 V. Lead acid, SLA, Gel Cell, and other battery types are all compatible.

* Using auxiliary power/battery input. Minimum is ~4.0 V without it.
*** 50 Amps continuous. Derate for wire temperatures above 70 Deg C.

Watt's Up Meter

Power	0-6554 Watts	0.1 W
Charge	0-65 Amp hours**	0.001 Ah
Energy	0-6554 Watthours**	0.1 Wh

Measures up to eight DC values with much higher precision.

Amp-Hours: (0 - 65)
Watt-hours: (0 - 6554)
Amps: (0-100 peak)
Watts: (0 - 6554)
Peak Amps & peak Watts
Minimum voltage ("sags")
Voltage: (0 - 60)

Works with 12, 24, 36 or 48 volt batteries up to 60 V. Lead acid, SLA, Gel Cell, and other battery types are all compatible.

* Using auxiliary power/battery input. Minimum is ~4.0 V without it.
** Much higher at reduced resolution.
*** 50 Amps continuous, 3-wire connection. Derate for wire temperatures next to case above 70 Deg C.
