digital interfaces. The transmission rate of RS-485 can be up to 115.2K bps. The RS-485 inter-
face can be used to connect multiple power supplies, up to a maximum of 254 units. The maxi-
mum effective control distance can be up to 1000m.
Digital remote control is also available via optional GPIB (suffix G) and LAN (suffix E) interfaces.
1.6 ANALOG CONTROL
External reference signals, provided through the Programming Control port (see Table 2-4), can
be used to control the output voltage and current of the KLN 750W. The Programming Control
port allows control of output on/off and permits emergency shutdown of the output. Output sig-
nals allow remote monitoring of whether the unit is powered on, output on/off, alarm condition,
output voltage and current, and operating mode: Constant Current (CC) or Constant Voltage
(CV). Refer to PAR. 3.5 for further details on using external signals to control and monitor the
output.
1.7 FEATURES
1.7.1 DIGITAL CALIBRATION
The KLN 750W Power Supply features high stability and long intervals between calibration. The
unit contains no user-required internal adjustments. Calibration is done by means of software
(see Section 4).
1.7.2 PROTECTION
The following protection is provided: OVP (Overvoltage protection), OCP (overcurrent protec-
tion), OTP, (overtemperature protection) and blown fuse.
1.7.3 SAVING AND RECALLING SETTINGS
The KLN 750W offers 16 memory locations accessible from the front panel that can be used to
store a set of operating parameters for later use. For each location, the user can store voltage
and current values. The stored settings can then be recalled to quickly program the unit to the
predetermined setting. Refer to PAR. 3.3.6 and 3.3.7 for further details.
1.7.4 PARALLEL AND SERIES CONFIGURATIONS
Identical KLN 750W units may be configured in series (up to two units including master) or par-
allel (up to five units including master) configurations. Parallel configurations provide for auto-
matic current sharing (see PAR. 2.8 for details).
1.7.5 MISCELLANEOUS FEATURES
• Both positive and negative output ramps can be independently programmed (see PAR’s.
3.3.10 and 3.3.11).
• Last setting is automatically restored upon power-up. Output can be programmed to be
either on or off upon power-up (see PAR’s. 3.3.9).
• One key recall of up to 16 memory locations storing voltage and current settings (see
PAR’s. 3.3.26 and 3.3.7).
• Variable speed fan reduces noise and extends fan life.
• Non-gap stacking; No ventilation holes at top or bottom.
