The Lambda LDS-X-15 is a 15 VDC regulated power supply engineered to deliver stable, precision-regulated power in demanding technical environments. This convection-cooled unit combines tight voltage regulation, minimal output ripple, and automatic protection circuits to ensure reliable operation across temperature-sensitive and industrial applications. With selectable 105–127 VAC or 210–254 VAC input, the LDS-X-15 scales across a wide range of operating conditions while maintaining stringent electrical performance.
– Technical Specifications
Output: 15 ± 5% VDC; maximum 5.5 A at 40°C ambient (4.7 A with cover), derating to 3.6 A at 60°C ambient.
Input Power: 200 W; 105–127 VAC or 210–254 VAC (transformer tap selectable); 47–440 Hz frequency range (ratings apply 57–63 Hz).
Line & Load Regulation: 0.005% + 0.5 mV across input variations (105–254 VAC) and load transitions (no load to full load).
