Product Introduction

General Specification

Model No.	Output (Max.W)	Output (V)	Load (Min.A )	Load (Max.A)	Load Regulation（%）	Line Regulation（%）	Ripple & Noise（mV）
K250B4800521E1z	360	48	0	5.21	± 5	± 1	480
K360A4800750E1z	360	48	0	7.50	± 5	± 1	360

NOTE：

Ripple & Noise is measured by using 20MHz bandwidth limited oscilloscope and terminated each output with a 0.1uF ceramic capacitor & parallel with 47uF aluminum capacitor at full load and nominal line.

Line regulation is defined by changing ±10% of input voltage from nominal line at rated load.

Max. Power (W) ≥ Vo x Io
