The Sorensen DLM25-160 is a programmable DC power supply engineered for laboratory and industrial applications requiring precise voltage and current control. This 2U chassis unit delivers 0–25V at 0–160A with automatic crossover between constant voltage and constant current modes to match varying load conditions. The supply maintains exceptional regulation: voltage holding 0.05% of maximum rated output plus 2 mV, while current stability reaches 0.1% of maximum rated output. Transient response recovers within 1 ms to 1% of rated output voltage following 70%–100% or 100%–70% step load changes. Long-term stability is ±0.05% over 8 hours after warm-up at fixed line, load, and temperature conditions.
