   SERIES HSP OUTPUT CHARACTERISTICS
Specification Rating/Description Condition
Output setting
range
all except 48V: -80% to +10% (1) Of nominal output
48V only: -80% to +25% (1)
Source Effect Typical: 0.05% Nominal 15%
Maximum: 0.1%
Load Effect Typical: 0.05% 5 ~ 100% load; operation between 0 - 5% load results in increased ripple and degraded transient response.
Maximum: 0.1%
Temperature Effect Typical: 0.01% Per C (0 to 50C)
Maximum: 0.02%
Time Effect
(drift)
Typical: 0.05% 0.5 ~ 8.5 hrs
Maximum: 0.1%
Combined Effect
(source, load,
temperature
and time)
Typical: 0.15%  
Maximum: 0.3%
Startup Time Maximum: 1 Second Any source/load
Recovery
Characteristics
Excursion: <3% of nominal output 50 - 100% load
Recovery: 1000W: 100 μsec
1500W: 300 μsec
Return to 1% of setting
Ride through Minimum: 21.5 milliseconds From loss of source
to flag signal.
Hold-up Time Minimum: 5 milliseconds After signal flag.
Overshoot Turn on: +3% maximum Any source, 5% to 100% load.
Turn off: None
Error Sense 3.3V, 5V: 0.25V Voltage allowance per wire.
All others: 0.4V
Series Connection
(output floats)
  500V Maximum voltage off ground.
Parallel Connection
(for redundancy)
  Current shares within
5% of rated load.
5 ~ 100% load, hot swappable
Selective Overvoltage
shutdown
  Adjustable 100 ~ 140% of nominal;
factory set to 130%.
Latched, reset by cycling source power off.
Current Limiting   Constant current mode;
factory set at 110% of IO max.
Optional shutdown mode with 20 second delay.
Remote On/Off RC-1: Normally high Isolated form C or TTL.
RC-2: Normally low
Overtemperature   Thermostat, auto restart. With hysteresis
(1) External voltage programming only, otherwise -30% to +10%, -30% to +25% for 48V models.
