RoHS Compliant. Electronic Component Power Source. SL series is intended for installation as a component of a system. It is designed to meet CE standards, with conditions of acceptance often being: customer provided enclosure mounting, EMC filtering, and appropriate protection, and isolation devices. The SL series is not intended to be operated by end users as a stand-alone device. The SL series power supply can only be fully assessed when installed within a system, and as a component part within that system.
Please contact Spellman sales for details. Higher voltage models available on special order. The input current numbers above are worse case assuming the power supply is being operated at maximum power and low line conditions, taking efficiency and power factor into account.
There may be some restrictions on multiple option combinations. Please contact our Sales department for more details. The eSL Option provides a vacuum fluorescent front panel display and Ethernet connectivity. Both the 1U 1.
Using the front panel local controls the main menu has the following features:. Allows operation from either the local front panel or remotely via the Ethernet Category 5 connector. Provides information on the revisions of the hardware, firmware and IP address. Additionally the Diagnostics Menu provides information on the status of the internal low voltage housekeeping power supply voltages. A control board jumper is moved to make the power supply shut down if it ever operates in current mode.
This allows the user to set the current programming level as a trip point that will turn the power supply off with an Over Current fault if it ever tries to operate in Current Mode. A third control loop is installed in the power supply, a power loop. This power loop uses an analog multiplier chip to multiply the voltage and current feedback signals to create a power feedback signal.
The circuit is configured to trip the power supply off with an Over Power fault if the power loop ever tries to regulate. A control board jumper is moved such that the first arc sensed will shut the power supply off with an ARC fault. BPM Bipolar Master. This option configures two identical but opposite polarity units to function as a single tracking bipolar supply.
The voltage feedback of the master positive unit is provided to the voltage programming input of the slave negative unit. A front panel switch is provided to allow the power supply to either regulate in current mode or create an over current fault when operated in current mode, which will shut down the supply.
This is basically a switch selectable AOL option. Optional: Vac, three phase; 25 amps, maximum. Output Voltage:. Each model is available with positive or negative outputs. Local Output Controls:. Voltage and current are continuously adjustable over entire range via ten-turn potentiometers with lockable counting dials. Voltage Regulation:. Load: 0. Line: 0. Current Regulation:. Lower ripple available via special order.
Temperature Coefficient:. Temperature Range:. Forced air; inlet through side panels, outlet at rear panel. System Status Display:. Digital Interface:. Ethernet and RS digital interface implemented with 12 bits of resolution. Input Line Connector:.
