Taiwan production, high quality, cute appearance, stable and reliable performance, Display high precision and with backlight.
dB: -20~+5dB; 0dB=1.288V+/-10%, calibalated; DCR= 650Ω, If=450uA; Lamp: White LED x1pcs ,10~20mA (Original design has no resistor inside, so need extra one to work); Led Lamp voltage : 2.2~2.6V
So, you need the extra resistor : 270Ω 1/4W ,if VDC=5V 390Ω 1/4W ,if VAC/DC=6.3V 1000Ω 1/2W ,if VAC/DC=12.6V
Also need external resistor, diode, capacitor (if 1Khz 0dB=1.288Vrms, R1=470Ω,VR1=100Ω, or R1+VR1=500Ω)
Dimension: 35.0x35.0x38.0mm, WxHxD; View size: φ34.0mm; Mounting hole/pitch: φ3.5mm/28.0x28.0mm; Note: On the center 2 pins are for meter coil, other 2 pins are for LED
