The Yokogawa 701934 is an external probe power supply engineered to deliver stable, regulated power to multiple Yokogawa probe types simultaneously. It accommodates current probes, FET probes, differential probes, and large current probes, with four independent power supply connectors supporting parallel operation. The unit outputs ±12 V ±0.5 V at a combined 2.5 A per rail across all four outputs, drawing up to 170 VA from a standard AC 100–240 V mains supply (50/60 Hz). Designed for integration with Yokogawa SL1000 and SL1400 data loggers, the 701934 eliminates the need for external power infrastructure when deploying multi-probe measurement systems.

– Compatibility & Integration
The 701934 interfaces with DL probe power connectors and works with current probes, FET probes, and differential probes. Probes equipped with Yokogawa probe I/F connectors (701927, 701928, 701929 series) draw power directly from the host data logger front panel and do not require this external supply.
Operating Environment: 0–40°C, 80% RH max (non-condensing); Storage: −10–50°C, 80% RH max (non-condensing)
