The CCCV parameters cannot be read or adjusted via SNMP.
Over Power and Over Current Protection
The MPC‑1250 for CCCV charging will act as a current source when overloaded. The current limit
is fixed at 47 A. The output voltage will be reduced in order to maintain 47 A.
The MPC will run at 47 A indefinitely without shutting down. External breakers are not required to
protect the MPC; however, an external breaker may be necessary to protect end use equipment.
Low current loads with wires not sized for 47 A should be protected by a breaker or fuse.
In addition to the 47 A current limit, the MPC‑1250 for CCCV charging has an Over Power limit.
When Vset or Vtop are set above 27 V, the MPC is capable of delivering more than 1250 W. To
prevent overloading the input sources, the MPC will regulate the output power to 1300 W by
lowering the output voltage. The output voltage will rise to the user set value when the load is
decreased below 1300 W.
