VK-4W Series
4W 4:1 Regulated Single & Dual output
The VK-4W series is a family of cost effective 4W single & dual output DC-DC converters. These converters are consisted with Nickle-coated copper in a 24-pin DIL package with high performance features such as 1500 ~ 3500 VDC input / output isolation voltage, continuous short circuit protection with automatic restart and tight line / load regulation. Devices are encapsulated using flame retardant resin. Input voltages of 24 and 48 with output voltage of 3.3, 5, 7.2, 9, 12, 15, 18, 24, ±3.3, ±5, ±7.2, ±9, ±12, ±15, ±18 and ±24 VDC. High performance features include high efficiency operation up to 86% and output voltage accuracy of ±1% maximum.
● Wide 4:1 Input Range
● 1500 VDC Isolation, Up to 3500 VDC
● Continuous Short Circuit Protection
● Efficiency up to 86%
● Operating Temperature Range -40 ~ 95°C max.
