VSD400 series

VSD400 series is designed as one kind of tracking type converter modules with compact,solid state and high performance which packaged in industry standard. It employ type servo loops for lag free tracking at rates to 3600°/sec.All provide for standard "converter busy"and"inhibit"interface,and are transformer isolated.

VSD400 series haseight features:the first one is binary or BCD outputs;the second is high tracking rates (VSDH/VRDH types);the third is stardard 3.12"*2.62".82"module size;the forth is DTL/TTL,LS,or CMOS compatibility(VSDH/VRDH Binary Types);the fifth is stardard inhibit and converter busy interface;the sixth is internal 60 Hz transformers (VSDH/VRDH Binary types);the seventh is wideband operation;the ninth is no trims or adjustments.

Economy Series VSD/VRD converters of VSD400 series are characterized for operation at temperatures from 0° to +70,rates to 720° /sec,from standard plus 5 volt supplies.Reliability has not been sacrificed as hybrid circuitry is employed and is manufactured under strict quality control.Outputs are 14 or 12 bit binary and are DTL/TTL compatible.Precision Series VSDH/VRDH converters are a newer design which provides significantly higher tracking rates(to 3600° /sec),wideband operation,and are available in 14 or 12 bit binary as well as 3 or 4 decade BCD.The binary types are available with low power schottky or CMOS logic (with variable logic level) for lower power consumption in addition to stardard DTL /TTL logic , and they contain internal transformers for 6 Hz operation. The BCD types are DTL/TTL compatible. The 12 bit bianry and BCD types do not require a minus 15 volt supply. BCD units are offsettable by application of from 0 to +15 volts at pin PA,by ±0.5° for 4 decade units and ±2° for 3 decade units.
