SIM928 - Isolated Voltage Source

±20 V isolated voltage source Ultra-low noise output Two switchable, recharging batteries for continuous operation Battery lifetime: 1000 charge cycles Output floats to ±40 V Short-circuit protected SIM928 Rechargeable Isolated Voltage Source The SIM928 Isolated Voltage Source is ideal for applications where ultra-clean DC voltage is required. Voltage can be set between ±20 VDC with millivolt resolution, and the source can drive up to ±10 mA. The output circuit is optically isolated from all earth-referenced charging circuitry, providing maximum flexibility and noise immunity. The system can float to ±40 V, and the output is short-circuit protected . ... click for SIM928 Tech Support Programming Examples MSDS 3D Step File Volatility Statement SIM Modules Scientific Instruments SIM Modules Sci. Instruments SIM928 Isolated Voltage Source At the heart of the SIM928 are two independent nickel-metal-hydride rechargeable batteries, each providing up to 12 hours of operation under full load conditions. When a battery is nearly depleted, the SIM928 automatically switches in a second battery. The switchover between batteries is virtually glitch-free, giving you uninterrupted power around the clock. The depleted battery is automatically charged to capacity in about 5 hours. The batteries are guaranteed for 1000 charging cycles, and SRS offers replacement battery sets. SIM928 Output Noise X SIM928 Output Noise SIM928 Rechargeable Isolated Voltage Source In applications that occur over long time intervals, starting with a fully charged battery may be desirable. A battery charge override feature allows you to manually switch in the fully charged battery (assuming it is in “ready” state) at any time. Banana binding posts are provided for the + terminal, - terminal and chassis ground. SIM928 Specifications ±20 V, 1 mV resolution ±40 V (common mode to ground) 10 µVrms (1 kHz bandwidth) Short-circuit duration 2 (1 operating, 1 charging/standby) Nickel metal hydride 12 hrs.
