Overload Protection - Lambda LJS-13A Series Instruction Manual

STORAGE TIME — 16 ms min. at full rated current, maximum rated output voltage, and 105 VAC input.
OVERSHOOT — No overshoot under conditions of power turn-on, turn-off, or power failure.
INPUT

Watts*. For operation at frequencies above 440 Hz,
consult factory.

INPUT FUSE — Fuse F1 protects the input wiring to the power supply. Overload of power supply does
not cause fuse failure.
OVERLOAD PROTECTION
Electrical External . . . ... . . . . . Automatic electronic current limiting circuit, limits
output current to a preset safe value. Automatic
current limiting protects the load and power supply
when external overloads and direct shorts occur.
Internal ........ +... . . . . . Fuse F1 provides prevention against internal circuit
failure.
OVERVOLTAGE PROTECTION — All LJS-13A models include fixed built-in overvoltage protection
circuits which prevent damage to the load caused by excessive power supply output voltage. See table 7
below for overvoltage protector firing ranges.

INPUT AND OUTPUT CONNECTIONS — Terminal block on front of chassis. Reed-Prince no. 2 screw-
driver is required for terminal screws.
OPERATING AMBIENT TEMPERATURE RANGE AND DUTY CYCLE — Continuous duty from 0°C
to 71°C ambient with corresponding load current ratings for all modes of operation.
