Wattable is a powerful tool for those who work with electric power and have to take decisions quickly and precisely. This app calculates Watts, Ampere, Ohms and the reduction in voltage in the passive elements (Voltage Drop). 


It is a useful tool to: 


- Calculate your system power 


- Calculate your system amperage 


- Calculate your system voltage drop and check if it is admittable (more than 4%) 


Made for different users, from electricians to live music touring, 


It is an easy, fast and accurate tool which does not require an internet connection to work. 


With the beautiful and immediate, user interface you can select the known parameters of your system (e.g. Volt, Watt, Power Factor, Cable Lenght and Ampere) by a handy interface and quickly get the required datum, both in single phase and three phase systems.

INSTRUCTIONS:


TAB 1 AC

Let you calculate electric power (KW-KVA) and amperage (A) of an alternating current (AC) system,

when you have just one of theese two datas, assuming you know voltage (V) and power factor (cos fi). Single Phase voltage, depending on the nation you operate in, is 230v or 110v. Three Phase voltage, depending on the nation you operate in, is 400v or 208v. Power factor (cos fi), if unknown, can be considered 0,9 for mixed loads; it is 1 just for resistive loads, e.g. conventional bulbs. Inserting KW value (w x 1000) you can calculate amperage ( in three phase systems amperage value is considered per each phase of three, assuming load is well balanced).

KWA/A switch let you transform values from KW to KVA, that is another power expression not considering power factor.

Numbers can be inserted by a special keybord.


TAB 2 OHM

Let you calculate resistance and amperage in direct currrent (DC), when you have just one of theese two datas, assuming you know voltage. Numbers can be inserted by a special keybord.


TAB 3 DELTA V

Let you calculate voltage drop percentage (delta V) of an electric load.

Result is displayed in green if the value is less than 4%, safe condition,

in red if the value is more than 4%, unsafe condition.

You need to know cable length (in meters), amperage (A), tension (V), power factor (cos fi) and conductor dimension (mm2)
