DIO1: Ethernet/USB/RS232 Digital Interface.....$350
Can be used to monitor and/or control output voltage and current. Includes isolated Ethernet (10/100 Mbps), RS232, and USB (RS485 option “DIO2” available) interfaces, utilizing 16 bit DAC and ADC. This option incorporates the “E” (Enable) option. (Not available with G1, DIO2, or Auxiliary Output options.) Download Instruction Sheet & Drivers

DIO2: Ethernet/USB/RS232/RS485 Digital Interface.....$375
Can be used to monitor and/or control output voltage and current. Includes isolated Ethernet (10/100 Mbps), RS232, RS485 and USB interfaces, utilizing 16 bit DAC and ADC. This option incorporates the “E” (Enable) option. (Not available with G1, DIO1, or Auxiliary Output options.) Download Instruction Sheet & Drivers

E: Output Enable: ............$0
To enable the DC output, the Inhibit terminal must be tied to the -DC output. An open collector or contact closure can be used.

E1: Output Blocking Protection Diode ...........$15
Used for battery charging applications. Derate output by 10%. (Not available with N or P options.)

F: Moisture/Fungus Proofing ...........$50
Can be furnished with a moisture and fungus resistant varnish applied to interior surfaces.

G1: Alarm with Relay Contacts (Single Output models) ...........$25
Form C alarm contacts that change state when output voltage deviates ±2Vdc (5v to 47v models) or ±3Vdc (48v to 135v models) from nominal. To order, add suffix "G1" to model number. (Not available with Auxiliary Output or DIO options.)

G3: Output Indicator(s) (DC on) ...........$20
Front panel mounted green LED(s).

H: Handles ............$15

M: Bus Bar Cover ...........$20
Protects exposed terminals from contact.

M3: Digital Voltage and Current Meters ...........$120

N: N+1 Redundancy ...........$50
Includes “P” (Parallelable) option and “E1” (Output Blocking Protection Diode) options. Allows up to 4 like models to be wired in N+1 redundancy. An internal isolation OR-ing diode is included in each power supply. Current share accuracy is ±5% (typical). Power supply output current must be derated by 10%.

P: Parallelable ...........$30
Included in the “N” (N+1 Redundancy) option listed above: Allows up to 4 like models to be directly wired in parallel for increased current capability. Current share accuracy is ±5% (typical). Power supply output current must be derated by 5%.

S: Chassis Slides ...........$120
For racks having rear mounting rails spaced 18” to 24” behind the front panels. (Rack Mounting models only.)

Auxiliary Output: Choose desired voltage from the ‘Optional Auxiliary Output’ table for the Rack Mounting Models or the Benchtop Models. To order, use the ‘Model’ column to determine suffix and see the Rack Mounting Models or the Benchtop Models for cost increase. (Not available with DIO1, DIO2, C1 or G1 options.)
