Voltage and Current Monitoring (Included with option M3)$15.00 
 
 

For models with no programming or with 0-10v programming (option “C6”):

Voltage Monitor Terminal: Permits remote monitoring of output voltage, stepped down by a ratio of 10:1 (for 3.3v to
90v models) or 100:1 (for 100v to 150v models). Accuracy is 0.5% of maximum rated output voltage.
Current Monitor Terminal: For models with greater than 10 amps output current: permits remote monitoring of output
current, stepped down by a ratio of 100 mV/Amp (accuracy is 1% of maximum rated output current). For models with
less than 10 amps output current: permits remote monitoring of output current, stepped down by a ratio of 1000 mV/Amp.

(Accuracy is 1% of maximum rated output current or ±15 mA, whichever is greater.)

For models with 0-5v programming (option “C5”):

Voltage Monitor Terminal: Permits remote monitoring of output voltage, stepped down by a ratio of 10:1 (for 3.3v to
45v models) or 100:1 (for 48v to 150v models). Accuracy is 0.5% of maximum rated output voltage.
Current Monitor Terminal: For models with greater than 45 amps output current: permits remote monitoring of output
current, stepped down by a ratio of 10 mV/Amp. For models with from 5 amps to 45 amps output current: permits remote monitoring of output current, stepped down by a ratio of 100 mV/Amp. For models with less than 4.5 amps output current: permits remote monitoring of output current, stepped down by a ratio of 1000 mV/Amp.
(Accuracy is 1% of maximum rated output current or ±15 mA, whichever is greater.)

(When monitoring the output voltage and/or current by means of the monitor terminals, the use of an instrument having an
input impedance of at least 10 megohms is recommended.)

    
Latching Overcurrent control$15.00 
 
  If current is greater than 15% of the maximum rated output current, the power supply latches off. Reset by momentarily removing AC input power. This option is included with Option A2. (Available on Single Output models only. Not available with option A1.)

Output Redundancy Options 
 
 

N+1 Redundancy (Available on Single Output models only.)
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. This
option forces equal current sharing among like model supplies. The DC output load lines and remote sense lines may be directly
connected in parallel and all 'S bus' terminals must be connected together. The output voltage of each supply is individually set so
that the difference between the highest and the lowest is less than 100 mv. The current limiting set point of each supply should be
set at equal value. Power supply output current must be derated by 10%.
Includes:

  • Voltage and current monitoring (Option C7).
  • Output blocking protection diode (Option E1).
$110.00
 

'OR-ing' or 'Blocking Diode' Redundancy
Redundancy is attained by simply wiring two units in parallel. Derate output by 10%. (Available on Single Output models only. Not
available with options C9, E5.)
Includes:

  • Non-latching OVP set 15% above rated output (Option A2).
  • Alarm with relay contacts that close when output voltage drops more than 10% below nominal (Option G1).
  • Output blocking protection diode (Option E1).
  • Remote sensing.
$210.00
  
Final Test Data$35.00 
 
  Final test data also includes an extended 8 hour burn-in.
    
Digital Voltage and Current Meters$150.00 
 
  Voltmeter accuracy is 0.5% ±1 LSB; current meter accuracy is 1% ±1 LSB.
    
Resistive Programming$110.00 
 
  Output voltage and current may be programmed from 0 to rated output. Programming: ohms per volt out = 10k÷VRated ±5%. Program resistors are connected from 'V pgrm' to '?Sense' and 'I pgrm' to '?Rtn'. (Not available with options C1, C2, C5, C6, G1,G2, G5,J3.)
