-LF *¹

Floating ground
isolating high voltage return from chassis ground (50 V max)
All equipment that connects to the remote control connector (TB1) must be on the floating ground in case this feature is intended to be used. (This option cannot be used for the current flow measure to the load, and the floating high-voltage power supply.)
FAQ: What is floating ground?

-LMs *¹ *²

Parallel operation mode
One primary unit can control up to two Boosters (replicas) units
(sum of maximum rating output must be under 18 kW)

-LOc *²

Overcurrent protection with shutdown

-LW *¹

Slow start (ramp start)
It takes around 10 seconds from turning on the OUTPUT switch or remote switch to reach the maximum rated voltage
about 5 seconds at half the maximum rated voltage as output voltage.

-L(200V)

Input voltage 200 Vac ±10%, three-phase
(Input current: approx 105% of AC 208 Vac)

-L(220V)

Input voltage 220 Vac ±10%, three-phase
(Input current: approx 95% of AC 208 Vac)

-L(230V)

Input voltage 230 Vac ±10%, three-phase
(Input current: approx 90% of AC 208 Vac)

-L(400V)

Input voltage 400Vac ±10%, three-phase
[Input current] 3.0 kW/3.2 kW: 5.5 A typ, 4.0 kW: 8 A typ, 4.6 kW: 8.5 A typ, 6.0 kW/6.4 kW: 11 A typ

-L(3m)

The length of the shielded high voltage output cable is changed to 3 meters.

-L(5m)

The length of the shielded high voltage output cable is changed to 5 meters. (only for ≤40 kV models)

-L(7m)

The length of the shielded high voltage output cable is changed to 7 meters. (only for ≤15 kV models)

1. In case selecting -LMs option with -LF option or -LW option, all AK series which connected as master/slave need to equip -LF option and -LW option.
2. If you want the output shutdown at overcurrent in parallel connection, install the -LOc option only to the primary unit (available with other options) but not to boosters (available with different options). The shutdown operation at overcurrent is available only for the combination above. Note that the boosters (replicas) are not equipped with the -LOc option. When you use the boosters individually, the standard CC/CV mode specification is provided.
