May alam po ba kayong power meter na suitable gamitin for standby power (phantom load) measurement? Okay na po kaya yung Voltcraft Energy Logger 3500 na available sa Alexan? Yung Yokogawa WT210 kasi ay masyado ng mahal e.

Sa e-gizmo, may AC Power Analyzer kit, wala nga lang buil-in display so you'll have to interface sa PC. Hanngang 10A current capacity lang ata so thats about 2.2KVA load ang pwede ma-measure. Nasa 1.3K etotlang ata yung kit. Take note wala enclosure yun. If you need a built-in display and data logging capability ... pm mo lang ako, I can help you there. Isa ito sa favorite subject ko na gustong gusto ko talaga gawin ... power/energy monitoring and logging.

OK ang Energy Logger. 1500 nabili ko sa Alexan. May SD card slot para pang store ng data.

Mura lang pala ... yung mga nacheck ko kasi dati na locally available nasa 3K pataas ang presyo. Pwede kaya ma-hack yan sir motion para mas mataas and current capacity as in gamitin as secondary household power meter?

Salamat po sa reply, mga sir. May study po kasi ako about standby power consumption, gagawa rin po ako ng smart power strip. Ang problema ko lang po ay walang current sensor IC na mabilhan dito sa atin.

Aside from real power reading at KW-hr reading, may line voltage, current, VA and power factor readings siya. And I believe all of these can be logged.

Sir, accurate kaya po sya for power reading for small loads? Yun pong mga below 1W? OK po kaya na maglalagay na lang ako ng isang extra load na mataas ang consumption, tapos po kunin ko na lang yung difference para masukat ko yung small load?

Hindi ako sure gaano ka accurate. I assume it's as good as a generic digital multimeter. I used it to measure power consumption of the aircon as well as my DSL modem, router and NAS setup. Mukhang believable naman ang readings. But I don't know about 1W or below measurements. The readings have 0.1W resolution.

Ah sige po, sir. Try ko na rin, di naman sya masyadong mahal.

rjmarqueses · « **Reply #9 on:** December 03, 2011, 09:05:55 AM »

Pero mukhang mas ok po sya sa Kill-a-Watt power meter, 1W lang po kasi ang resolution nun.
